WebHis Geochemistry study combines topics in areas such as Nappe, Siliciclastic, Kerogen, Source rock and East European Craton. The study incorporates disciplines such as Maturity, Weathering, Hopanoids, Vitrinite and Carbon in addition to Organic matter. His research integrates issues of Mineralogy and Pyrene in his study of Environmental chemistry. Webcarbonate is highly enriched in continental shelf areas, and thus the tsunami sediments indicate they predominantly originated from a shallow marine environment. Average Sr/Ca ratio (0.0054) is similar to the average levels seen in continental shelf areas (Guebuem et al. 1999;Mu¨ller 1966; Yan and Tang 2009).
