Geochemistry is a fantastically broad discipline, and is one of the most powerful tools in the Earth Sciences.
It is concerned with chemical and isotopic analysis of substances as diverse as meteorite fragments, a chunk of coral, or a diamond.
An understanding of geochemical methods allows us to date the Earth, know how much rain fell in the Red Sea twenty-thousand years ago, or place limits on the composition of the mantle.
These methods are used extensively across the spectrum of the Earth Sciences, and provide data which complement what we can ascertain from Geophysics and other disciplines.
