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.

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).
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 ...
Regional geochemistry is the study of the spatial variation in the chemical composition of materials at the surface of the Earth, on a scale of tens to thousands of kilometres. Important parameters to consider when designing or evaluating a geochemical survey are:
The Goldschmidt classification, [1] [2] developed by Victor Goldschmidt (1888–1947), is a geochemical classification which groups the chemical elements within the Earth according to their preferred host phases into lithophile (rock-loving), siderophile (iron-loving), chalcophile (sulfide ore-loving or chalcogen-loving), and atmophile (gas-loving) or volatile (the element, or a compound in ...
