The P.I. intends to demonstrate the integration of field geology with quantitative laboratory investigations, geophysical modeling, and geochemical studies in the systematic examination of Precambrian sedimentary basins. This work will allow for the deciphering of long-term continental evolution as well as the history of oceans and atmosphere, throughout most of earth history. Two projects focus on the goals; the first will undertake an analysis of Proterozoic continental lithosphere trough investigations of the geometry and tectonics of foreland basins. The second project will investigate the possible long-term chemical changes in the Precambrian atmosphere and oceans. The key study of this work will be a sedimentologic/geochemical analysis of Precambrian carbonate sediments and depositional systems.

P.I.打算在对前寒武纪沉积盆地的系统检查中证明现场地质与定量实验室研究，地球物理模型和地球化学研究的整合。 这项工作将允许在地球大部分地区的大部分时间里对长期大陆进化以及海洋和大气的历史进行解密。 两个项目专注于目标；首先将对植物学大陆岩石圈槽对前陆盆地的几何形状和构造学的研究进行分析。 第二个项目将调查前寒武纪大气和海洋中可能的长期化学变化。 这项工作的关键研究将是对前寒武纪碳酸盐沉积物和沉积系统的沉积/地球化学分析。
