地球科学哲学博士-沉积地质学

石溪的沉积地质研究计划将地球化学与野外，岩石学和地层学研究相结合。陆源沉积岩的痕量元素和同位素研究提供了有关其起源，年龄和组成的信息，可深入了解地壳演化的各种问题，包括沉积物俯冲，大陆壳和沉积质量的增长以及沉积岩的再循环。碳酸盐岩及其成岩作用是利用多种方法进行研究的另一个重要领域。岩相学与微量分析技术，微量元素以及稳定同位素和放射性同位素结合，以重建成岩环境和古水文系统的理化特征。重点还放在岩水相互作用的定量建模上。碎屑和碳酸盐岩研究中，田野调查的一个重要组成部分很常见。分析设施包括该部门的电子微探针，光
Research initiatives in sedimentary geology at Stony Brook integrate geochemistry with field, petrologic, and stratigraphic studies. Trace element and isotopic studies of terrigenous sedimentary rocks provide information on their provenance, age, and composition, which yield insight to broader issues of crustal evolution, including sediment subduction, growth of continental crust and the sedimentary mass, and recycling of sedimentary rocks. Carbonate rocks and their diagenesis are another important area of research that utilizes a wide range of approaches. Petrography is combined with microanalytical techniques for trace elements and both stable and radiogenic isotopes to reconstruct the diagenetic environments and the physicochemical characteristics of paleohydrologic systems. Emphasis is also placed on the quantitative modeling of rock-water interaction. A strong component of fieldwork is common for studies of both clastics and carbonates. Analytical facilities include the department's electron microprobe, optical and cathodoluminescence petrography and electron microscopy facilities, a mass spectrometry lab, a M'ssbauer lab, DCP and ion chromatography labs, X-ray diffraction facilities, and a variety of facilities at the NSLS.
