2-I used stable isotopes of lake sediments, rocks and fossils to reconstruct paleo-environments
3-I used Mossbauer spectroscopy to asses valences and site characteristics of iron in geological including rocks and silicified woods.
4- I studied geochemistry, mineralogy, and stable isotope signatures in petrified woods
