Organic geochemistry, the study of the role of processes and compounds that are derived from living or once-living organisms. [13] Photogeochemistry is the study of light-induced chemical reactions that occur or may occur among natural components of the Earth's surface. [14]
Biogeochemistry is the scientific discipline that involves the study of the chemical, physical, geological, and biological processes and reactions that govern the composition of the natural environment (including the biosphere, the cryosphere, the hydrosphere, the pedosphere, the atmosphere, and the lithosphere).
Geomorphology: the study of landforms and the processes that create them. Hydrogeology: the study of the origin, occurrence and movement of groundwater water in a subsurface geological system. Igneous petrology: the study of igneous processes such as igneous differentiation, fractional crystallization, intrusive and volcanological phenomena.
Clair Cameron Patterson (June 2, 1922 – December 5, 1995) [1] was an American geochemist.Born in Mitchellville, Iowa, Patterson graduated from Grinnell College.He later received his Ph.D. from the University of Chicago and spent his entire professional career at the California Institute of Technology (Caltech).
A geologist is a contributor to the science of geology.Geologists are also known as earth scientists or geoscientists.. The following is a list of notable geologists. Many have received such awards as the Penrose Medal or the Wollaston Medal, or have been inducted into the National Academy of Sciences or the Royal Society.
Geochemical modeling is used in a variety of fields, including environmental protection and remediation, [1] the petroleum industry, and economic geology. [2] Models can be constructed, for example, to understand the composition of natural waters; the mobility and breakdown of contaminants in flowing groundwater or surface water; the ion speciation of plant nutrients in soil and of regulated ...
Isotope geochemistry is an aspect of geology based upon the study of natural variations in the relative abundances of isotopes of various elements.Variations in isotopic abundance are measured by isotope-ratio mass spectrometry, and can reveal information about the ages and origins of rock, air or water bodies, or processes of mixing between them.
Geologists broadly study the properties and processes of Earth and other terrestrial planets. Geologists use a wide variety of methods to understand the Earth's structure and evolution, including fieldwork , rock description , geophysical techniques , chemical analysis , physical experiments , and numerical modelling .
