Stony Brook's sedimentary geology research combines geochemistry with field observations, petrology, and stratigraphy. Analyzing trace elements and isotopes in sedimentary rocks reveals details about their origin, age, and makeup, offering clues about crustal development, sediment recycling, and continental growth. Carbonate rock studies, particularly their diagenesis, employ diverse methods, merging petrography with microanalysis of trace elements and isotopes to understand ancient hydrologic conditions. Quantitative modeling of rock-water interactions is another key focus. Field research plays a vital role in both clastic and carbonate investigations. The department provides extensive analytical resources, including electron microprobes, microscopy equipment, mass spectrometers, X-ray diffraction tools, and access to NSLS facilities.
