geochemical
Relating to rock chemistry
Geochemical relates to the chemistry of the earth—the composition, distribution, and cycling of chemical elements in rocks, minerals, soils, and water.
Scientists conduct geochemical analyses to understand ore deposits, groundwater contamination, or climate history preserved in ice cores.
Geochemical signatures in the rock samples revealed volcanic origins.
