Environmental science is an expression encompassing the wide range of scientific disciplines that need to be brought together to understand and manage the natural environment and the many interactions among physical, chemical, and biological components. Environmental Science provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems.[1] Individuals may operate as Environmental scientists or a group of scientists may work together pooling their individual skills. The most common model for the delivery of Environmental science is through the work of an individual scientist or small team drawing on the peer-reviewed, published work of many other scientists throughout the world.

The composition of the Earth:

Lithosphere (5-70 km, solid and rocky, 5 km thick under the oceans and up to 70 km thick under the continents). It composes of:
sedimentary cover (10 km)
Sial (granitic in composition)
Sima (basaltic in composition)

Rock cycle


Rocks are defined as a component of the EarthЎ¶s crust, composed of one or more minerals with geologic extension

Rocks are classified into:

- Primary - Igneous rocks

- Secondary - Sedimentary rocks

- Metamorphic rocks

The metamorphic rocks are secondary rocks formed from pre-existing igneous, sedimentary, and/or prior metamorphic rocks, which are subjected to physicochemical conditions (P, T, and chemical active fluids) higher than that at the earthЎ¶s surface. The yielded metamorphic rocks differ than the original ones in mineralogy, structure (textures), and/or chemical composition. Note: Metamorphism should be occur in solid state.
Due to higher P-T conditions, metamorphic rocks undergo partial melting and a hybrid rock between igneous and metamorphic, know as migmatites, could form.

Academic goals: to deduce the following
Protolith (original rock) composition
Grade and conditions of metamorphism
Tectonic setting under which the metamorphism have done
- Applied goals: Metamorphic rocks like other rock types hosted mineral resources e.g:

Graphite, Talc, Magnesite, Asbestos, Corundum, vermiculites, garnets, etc.
- They used also as ornamental stones as Slates, Marbles, gneisses, metaconglomerates, greenstones and others

Typpes of Metamorphysm
Types of metamorphism

ѓПOn the basis of (i) Geological setting, and (ii) agents of metamorphism, the type of metamorphism includes:

- Regional extent (over a wide area)

- Orogenic metamorphism (T, P, active fluids)

- Ocean floor metamorphism (T)

- Subduction zone metamorphism (HP/LT)

- Burial metamohism (LT/LP)

- Local extent (local area)

- Contact or thermal metamorphism (T)

- Cataclastic or shear zone metamorphism (P)

- Hydrothermal metamorphism (active fluids)

- Impact or shock metamorphism (extreme P-T)

A1: Orogenic metamorphism
(Regional or dynamothermal metamorphism)

Features of orogenic metamorphism :
- Where?: Restricted to orogenic belts and extent over distance of hundreds to southlands Kms, e.g. East-African orogen

The agents of metamorphism: include T, P & active chemical solution
Time duration is long (million or tens of millions years)
The yielded rocks suffered deformation and recrystallization, and exhibit penetrative fabric with preferred orientation of mineral grains. They could suffered phases of crystallization and deformation
At higher P-T conditions, partial to complete melting may accompanied and both migmatites and granites may associates, or granulite could be develop.


A2: Ocean-floor metamorphism

Features of ocean-floor metamorhism :
where?: Restricted to transformation of the oceanic crust at the vicinity of mid-ocean ridge
Occur in the upper part of the oceanic crust, typically in sheeted dykes
The agents of metamorphism include T & sea water percolation
- The yielded rocks are mostly basic (sheated dykes) in composition, with no penetrative fabric (non-foliated texture)

A3: Subduction zone metamorphism

Features of subduction zone metamorphism :
where?: At convergence plate margins, where subduction of cold oceanic lithosphere and overlying sediments against an adjacent continental or oceanic plate.
The agents of metamorphism include higher pressure, low temperature conditions
The yielded rocks contain high pressure mineral assemblage such glucophane, and kyanite should formed
To preserve such environment , the rock requires rapid uplift

A4: Burial metamorphism

Features of burial metamorhism :
Where?: in subsidence basins, where sediments and interlayered volcanics suffered low temperature regional metamorphism
Agent of metamorphism include low temperature-low pressure conditions due to burial affect without any influence of orogenesis or magmatic intrusions.
The yielded rocks lack schistosity and the original fabrics are largely preserved. So, the yielded rocks are distinguished only in thin section
- In Extensional regime, Diatathermal metamorphism is used

B1: Contact or thermal metamorphism

Features of Contact or thermal metamorphism :
Where ?: At vicinity of contacts with intrusive or extrusive igneous rock bodies
Agent of metamorphism is the higher temperature resulted from heat emanating from the magma, and sometimes by deformation connecting with the emplacement of the igneous bodies.
The zone of the contact metamorphism is known as contact aureole, various from meter to few kms.
The width of the zone depend up on:
1- volume of the magmatic bodies

2- nature of the magmatic bodies (basaltic or granitic composition)

3- The intrusion depth of magmatic bodies.

B1: Contact or thermal metamorphism, cont.

4- Type of country rocks (Shale, limestones or igneous rocks)

5- structures of the country rocks (cracks and fissures)

- Duration of metamorphism is short time (up to hundred years)

- The yielded rocks are generally fine grained and lack schistosity (hornfels)

In case of higher temperature influence, Pyrometamorphism, is used.
Migmatites could produced in such conditions.

B2- Cataclastic or shear zone metamorphism

Features of cataclastic or shear zone metamorphism :
where?: Restricted to the vicinity of faults of overthrusts in the upper crust level (brittle deformation)
Agents of metamorphism is pressure in form of mechanical forces.
The yielded rocks suffered crushing, granulation and pulverization (reducing in grain size).
The yielded rocks are non-foliated and braccia-like, cataclasite, mylonite, ultramylonite to pseudotachylite.

B2- Cataclastic or shear zone metamorphism

B3- Hydrothermal metamorphism

Features of hydrothermal metamorphism :
where?: Localized at interaction of hot, largely aqueous fluids (from igneous source) with country rocks.
Similar to regional ocean-floor metamorphism
the aqueous hydrothermal fluids usually transported via fractures and shear zones at some distance either near or far from their source
- The yielded rocks are mineralogically and chemically changed than the protolith and ore deposits are occasionally originated

If the gases instead the aqueous fluids, Pneumatolytic metamorphism, is used

B4- Impact or shock metamorphism

Features of impact metamorphism :
Where?: Impact of fall meteorites with different size on the EarthЎ¦s crust.
This impact yielded shock waves with extreme higher P-T conditions, up to 1000 kbar and 5000 ўXC
Duration time is very short, microsecond.
- The impacted rocks were vaporized, but in less condition, they melted to produce vesicular glass containing coesite and stishovite, as well as minute diamond

Earth''s Dynamic Systems
Metamorphism and Tectonics

Steady state geotherm: Is that curve defining the change in T as a function of depth in an area that is not experiencing any tectonic activity such as a stable shield or continental interior.

Transient geotherm: Is the geotherm in a tectonically active area, and will only prevail for a limited time period that depends on the duration and type of this tectonic event.

Geothermal gradient: Is the slope of the geotherm at a particular time in the history of the study area.

Metamorphic field gradient: Is a trajectory connecting the P-T conditions at the maximum T calculated for each metamorphic zone. According to England and Richardson (1977), the metamorphic field gradient has little physical meaning because peak temperatures in each metamorphic zone were reached at different times during the metamorphic history of the area.

An overview of metamorphism in relation to tectonic regimes:
The metamorphic facies series encountered in different tectonic regimes or settings can be summarized as follows, and are shown schematically on Figs. 1 and 2:
(a) Ridges and rift valleys: characterized by high geothermal gradients * contact and ocean floor metamorphism.
(b) Areas of magmatic activity; volcanic - plutonic complexes: greenschists * amphibolites * granulites.
(c) Areas of crustal thickening and mountain building: greenschists * amphibolites * granulites and type B eclogites (particularly if there are magmatic intrusions).
(d) Subduction zones: Characterized by low geothermal gradients: zeolite * pumpellyite-actinolite facies /lawsonite albite facies * blueschist facies * type C eclogites.

A- Convergent Plate Boundaries:
I- Subduction Zone metamorphism:
Rocks of the subducted plate are usually metamorphosed following "clockwise" P-T paths in which peak pressures are attained before peak temperatures. According to tectonic setting, subduction is of two "types":
(a) B-type subduction: where the oceanic crust is subducted beneath a continental or another oceanic plate. This type usually results in the formation of the "paired metamorphic belts" of Miyashiro, with blueschists and eclogites in the subducted plate close to the subduction thrust, and high T, low P amphibolite- and sandinite- facies rocks on the overriding plate, commonly forming an island arc in the case of ocean - ocean interaction (Figs. 3 and 4). Examples of this type include the Franciscan (with the Sierra Nevada) in the western U.S.A., and the Sanbagawa (and Abukuma) belts in Japan.
(b) A-type subduction: where the continental crust "attempts" to become subducted usually beneath another continental plate. Because of the low density of continental material, it is generally more difficult to subduct compared to the oceanic crust, and will have a tendency to "rebound" isostatically. Examples include the western Alps (Dora Maira), the Tauern Window (Austrian Alps; Fig. 5), and Saih Hatat (Oman).

While discussing subduction zone metamorphism, it is appropriate to discuss some of the problems associated with its rocks. The most important of these is the preservation of blueschist facies mineral assemblages, and the uplift of blueschists.

Preservation of Blueschists:
ē Most blueschists (and type C eclogites) are characterized by clockwise P-T paths, and may therefore undergo heating and decompression during their exhumation.
ē If the geothermal gradient prevailing during exhumation is sufficiently high, these rocks will pass through the greenschist, epidote amphibolite or amphibolite facies upon exhumation.
ē If exhumation rate is not rapid enough, these rocks will be overprinted by these later assemblages to such an extent that they may not survive their trip to the surface.
ē Draper and Bone (1974) suggested that the preservation of blueschists requires exhumation rates that cannot be accounted for by average erosional rates.
ē Hairpin shaped paths and their significance  underthrusting and refrigeration.

Models of blueschist and eclogite exhumation:
a) Platt''s model: Platt (1987) suggested that blueschists and type C eclogites formed by B-type subduction may be underplated (attached or accreted) to the overriding plate or mantle wedge. Such process leads the accretionary wedge to become thicker and tectonically unstable. This in turn leads to the development of normal faults along which the high P/T rocks can make their way back to the surface fairly rapidly without being significantly overprinted. This model is shown in Fig. 6. Note that a similar model can be tailored to type A subduction zones.
b) Cloos''s model: Cloos (1982) suggested that during B-type subduction, accretionary wedge pelitic material moving down the subduction zone will tend to flow back upwards by the forces of buoyancy, when it can then carry bits and pieces of the subducted slab (now metamorphosed under blueschist and eclogite facies conditions; Fig. 7). This model works only for tectonic mélanges, such as in the Franciscan.
c) Other models: Water melon seed model; delamination; Ö. etc.

Blueschists in time:
Most blueschists are Mesozoic in age, with some Paleozoic examples, and only a handful of Precambrian ones. Could this be due to Plate tectonics not operating during the Precambrian the way we think it does today? Or is it a function of differences in geotherms prevailing at those times? Post-Eocene blueschists are also very rare or non-existent. Can you think of a reason?

II- Thrusting and continent - continent collision:
Not all areas of continent Ė continent collision are characterized by high P/T metamorphism; many were found to belong to Miyashiroís high P, intermediate facies series; whereas others are associated with so much magmatic activity that they may be considered to belong to the ďregional Ė contactĒ type of metamorphism of Spear (1993). Examples of these two cases include:
1- The Himalayas (which have an inverted metamorphic gradient in which the Sill zone overlies the Ky zone, which in turn overlies the Gt and Bt zones (Fig. 8). Several models have been proposed to explain this inverted sequence and the P-T paths obtained. These are shown schematically in Figs. 9 and 10.
2- New England: The northern Appalachians are characterized by a complex Polymetamorphic history. The main event seems to have been Acadian, in which a continental fragment collided with N. America resulting in partial melting and the development of numerous igneous intrusions. Nappes containing sheet Ė like igneous intrusions were emplaced onto colder sheets. The overthrust nappes therefore had counterclockwise P-T paths, whereas the lower nappes were characterized by periods of isobaric heating followed by near isothermal loading (Fig. 11).

III- Metamorphism associated with ophiolite emplacement:
1- Subophiolitic metamorphic aureoles or soles and inverted metamorphic gradients.
2- Burial type metamorphism with a high P/T field gradient
3- Subduction zone metamorphism

B- Stable continental interiors and deep sedimentary basins:
These are characterized by burial metamorphism with clockwise P-T paths, and peak T in the greenschist to epidote amphibolite facies.

C- Divergent Plate Boundaries:
1- Ocean Floor Metamorphism:
2- Continental rifts: In such settings, it is very common to find ďmetamorphic core complexesĒ, defined as areas that are topographically high and that consist of igneous and metamorphic rocks that display anomalous deformation and metamorphism relative to the surrounding rocks. These complexes are structurally overlain by normally faulted sedimentary rocks. The boundary between the complexes and the sedimentary rocks is a low angle normal fault known as a ďdecollementĒ. Rocks of the metamorphic core complex are characterized by clockwise P-T paths of evolution, with segments of isothermal decompression, marking their rapid exhumation along these decollements. Examples include several areas in the Basin and Range province, and the Cordillera Darwin in Chile (Fig. 12).

Conservative Plate Boundaries:
1- Cataclasis and Mylonitization
2- Serpentinite diapirs and associated metasomatism.

Plate Boundaries

Transform Plate Boundaries
Transform plate boundaries are unique, in that the plates move horizontally past each other on strike-slip faults. Lithosphere is neither created nor destroyed.

The three major types of transform boundaries are: (1) a ridge-ridge transform, which connects two segments of a divergent plate boundary; (2) a ridge-trench transform, which connects a ridge and a trench; and (3) a trench-trench transform, which connects two convergent plate boundaries.

Transform plate boundaries are shearing zones where plates move past each other without diverging or converging. In the shearing process, secondary features are created, including parallel ridges and valleys, pull-apart basins, and belts of folds. Compression and extension develop only in small areas.

Oceanic fracture zones are prominent linear features that trend perpendicular to the oceanic ridge. They may be several kilometers wide and thousands of kilometers long. The structure and topography of oceanic fracture zones depend largely on two things: the temperature (or age) difference across the fracture, and the spreading rate of the oceanic ridge.

Continental transform fault zones are similar to oceanic transforms, but they lack fracture zone extensions.

Shallow earthquakes are common along transform plate boundaries; they are especially destructive on the continents.

Volcanism is rare along transform plate boundaries, but small amounts of basalt erupt locally from leaky transform faults.

Metamorphism in transform fault zones creates rocks with strongly sheared fabrics, as well as hydrated crustal and even mantle rocks.

Environmental Geology
Environmental Geology reflects the view held by a growing number of geologists that an integrated Earth system science approach provides essential insights into the workings of the whole Earth and is crucial to the development of scientific literacy. Unique, contemporary, and visually stunning, this new textbook guides the reader toward a personal understanding of Earth''s varied environments, the whole Earth system that connects them, and the local and global ramifications of natural events and human intervention.

EARTH: AN INTRODUCTION TO PHYSICAL GEOLOGY, by Edward J. Tarbuck, Frederick K. Lutgens, Dennis Tasa



In the consideration of the characteristic fossils of each successive period, a general account is given of their more important zoological characters and their relations to living forms; but the technical language of Zoology has been avoided, and the aid of illustrations has been freely called into use. It may therefore be hoped that the work may be found to be available for the purposes of both the Geological and the Zoological student; since it is essentially an outline of Historical Palśontology, and the student of either of the above-mentioned sciences must perforce possess some knowledge of the last. Whilst primarily intended for students, it may be added that the method of treatment adopted has been so far untechnical as not to render the work useless to the general reader who may desire Page vii to acquire some knowledge of a subject of such vast and universal interest.

University of California, Davis Land, Water
Atmospheric Science
Soils & Biogeochemistry

http://lawr.ucdavis.edu/undergrad_atm.htm - Atmospheric Science
Atmospheric science is the study of the layer of air that surrounds the planet. It includes all weather phenomena, such as frontal systems and clouds, as well as severe weather events such as hurricanes and tornadoes. Concerns regarding the effects of human activity on the quality of the air we breathe, and on possible global warming are also central to this field of study.

The Program. Modern meteorology is a quantitative science that is becoming increasingly computer oriented. In addition to the study of daily weather events, the program deals with fundamental physical processes that involve the general circulation of the atmosphere; mass and energy transfers at the planetary surface and within the atmosphere; solar and terrestrial radiation; atmospheric interaction with the biosphere; climate variations; air pollution meteorology; and developments in modern meteorological instrumentation. As well as providing a broad background in meteorology, the major includes an informal minor area to be chosen from mathematics, computer science, environmental studies, resource management or a physical or biological science.

UCD Atmospheric Science offers excellent opportunities for students. Small class sizes foster student-instructor interaction. Students can pursue topics in observations, instrumentation, theory, modeling and computation.

Our Bachelor of Science program conforms to the national accreditation standards set by the National Weather Service and the American Meteorological Society.

http://lawr.ucdavis.edu/undergrad_ers.htm - Environmental & Resource Science

The environmental and resource sciences major is a program for study of the biological, chemical, and physical features of environmental resources, and the economical and social considerations associated with their use, conservation, protection, and management and restoration. Students who choose this major include those with an interest in careers associated with environmental resource utilization and management, as well as those pursuing post-baccalaureate, academic, or professional training.

The Program. The curriculum for the major provides flexibility in meeting individual needs, interests, and objectives. At the same time, certain courses are required in the basic physical and biological sciences areas. Upper division general environmental resource sciences courses, a resource economics course, and a specified number of units of environmental and resource-oriented courses are required for all students in the major. Students select environmental and resource-oriented courses in consultation with and approval of the studentís adviser. Considerable care should be taken to ensure effective utilization of the flexibility of the major, and to meet individual academic and career objectives. Students may specialize their study by selecting one of the options within the major or, in consultation with their adviser, pursuing other specializations.

http://lawr.ucdavis.edu/undergrad_hyd.htm - Hydrology

The goal of the Hydrology Program is to meet the need for qualified hydrologists in the immediate and foreseeable future as identified by the National Academy of Sciences. Graduates of the program are equally ready to assume positions as practicing hydrologists with resource agencies or consulting firms or to seek advanced training at the graduate level.

The Hydrology Program offers a B.S. degree and a supplemental minor in hydrology in response to the need for a coherent hydrology curriculum. At present, the major is one of only two such programs in the country.

The Program. Hydrologists generally need strong backgrounds in physics, mathematics, chemistry, biology, geology, field methods, and computer methods. Knowledge of biology and chemistry is important for understanding modulators of water quality. Geology is essential for those working in groundwater hydrology. Field methods are necessary for observing and measuring hydrologic phenomena, and computer methods and mathematics are routinely needed for collectively analyzing field data and forecasting future system behavior.

The diverse and interdisciplinary hydrology major is designed to expose students to a broad range of hydrologic processes with course work that forms a basis for specialization in such areas as hydrobiology, hydrogeochemistry, irrigation/drainage, surface or groundwater hydrology (hydrogeology), and water management. Students in the major program complete a total of 180 units, including 72 units of rigorous course work in the natural sciences and mathematics, along with general education course work.
http://lawr.ucdavis.edu/undergrad_sws.htm - Soil & Water Science
Soil and water science is concerned with the use and protection of our land and water resources. The major teaches graduates sound scientific principles for managing soil and water resources to benefit both agriculture, forestry and the environment.

The Program. Major programs include land use, soil survey, soil management and conservation, plant nutrition, diagnostic technology, irrigation and drainage, water resources management, water quality, and related environmental problems. (For example, the emphasis on water quality would include more than the minimum number of units of physical and biological sciences, while an emphasis in resource allocation and land-use planning would include more courses in the social, political, and economic areas.)
