Some subfields of geochemistry are: [9] Aqueous geochemistry studies the role of various elements in watersheds, including copper, sulfur, mercury, and how elemental fluxes are exchanged through atmospheric-terrestrial-aquatic interactions. [10] Biogeochemistry is the field of study focusing on the effect of life on the chemistry of the Earth.
Some [who?] may use the terms biogeochemical cycle and geochemical cycle interchangeably because both cycles deal with Earth's reservoirs.However, a biogeochemical cycle refers to the chemical interactions in surface reservoirs such as the atmosphere, hydrosphere, lithosphere, and biosphere [citation needed] whereas a geochemical cycle refers to the chemical interactions that exist in crustal ...
Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages. [4] By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of ...
Geochemistry, Geophysics, Geosystems is a peer-reviewed open-access scientific journal covering research in Earth and planetary processes with a focus on understanding the Earth as a system. The journal is published by Wiley on behalf of the American Geophysical Union .
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 ...
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 ...
Petroleum geochemistry is a branch of geochemistry (the application of chemical concepts to understand geological systems) which deals specifically with petroleum and its origin, generation, and accumulation, as well as its extraction, refinement, and use.
Aqueous geochemistry studies the role of various elements in natural waters, including copper, sulfur, and mercury. Researchers in this field also study how elemental fluxes are exchanged through interactions between the atmosphere , the earth or soil (terrestrial interactions) and bodies of water (aquatic interactions).
