Description of this Geochemistry Website

Here we give very brief descriptions of most types of terrestrial and lunar igneous rocks, their regional distribution and classification, and examples of their geochemical trends and "fingerprints".

Clicking on the minature "thumbprints" will allow the diagrams to be shown at a larger size. Enough examples are shown for any new data to be typed.
