geochemists
Earth composition scientists
Geochemists are scientists who study the chemical composition of the earth—its rocks, minerals, soils, and waters.
They analyze how elements and compounds distribute themselves across geological formations and cycle through natural systems.
Geochemists work in fields from mining exploration to environmental monitoring: Geochemists tested the groundwater for contamination.
