1. There are many variables requiring complex calculations of geochemistry and hydrology. 2. In 1986 the IAGC launched its official journal, Applied Geochemistry . 3. Werner Stumm was an active researcher in several aspects of geochemistry . 4. MetPetDB differs from other Geochemistry relational databases ( e . g. 5. This hypothesis leans heavily on the techniques of petroleum geochemistry . 6. Often, assimilation can only be proven by detailed geochemistry . 7. Concurrently, advances in atomic physics stimulated investigations in stable isotope geochemistry . 8. Chemistry and the earth sciences intersect in areas like geochemistry and hydrology. 9. The main methods currently used for confirmation are absorption spectroscopy and geochemistry . 10. Kulp was professor of geochemistry at Columbia University between 1947 and 1965.
