Etymology: Geochemistry is the older term, built from "geo-" (Earth) and "chemistry," and the noun "geochemist" was formed from it by back-formation. That means speakers took the existing word "geochemistry" and read it as if it were a combination of a base and a suffix, then produced a new word for the person who practices the field. The usual pattern runs the other way, with a person-word such as "chemist" supplying the base and "-ist" added on, so "geochemist" reverses the expected construction. The word is a modern scientific coinage, so it has no ancient history behind it. Its parts are classical, drawing on Greek "ge" for Earth and "chemeia," the root of "chemistry," but the combined forms are products of recent scientific naming. The term describes a practitioner who studies how the chemical composition of rocks, minerals, water and the atmosphere changes through geological processes.
