9303966 Harris In this collaborative research, PIs will develop and evaluate criteria for recognizing stratigraphic sequences in outer-shelf and slope carbonate environments. Recognition of sequence boundaries in these settings is problematic because typical boundary criteria are not applicable--exposure events are absent and stratal geometries are difficult to extract from outcrop-scale exposures. PIs will combine stratigraphic, sedimentologic and biostratigraphic study of Ordovician and Silurian strata in the U.S. Great Basin to develop a sequence model; the sequences will be traced along dip and strike transects to evaluate changes in criteria usable in identifying sequence boundaries. This work will contribute not only to understanding Paleozoic history of the Great Basin, but also to developing sequence stratigraphic models for deeper-water carbonate units. Results will have use in both academia and industry.

小行星9303966 在这项合作研究中，PI将制定和评估识别外大陆架和斜坡碳酸盐岩环境中地层序列的标准。 在这些环境中识别层序边界是有问题的，因为典型的边界标准是不适用的-曝光事件是缺席的，地层几何形状是难以从露头规模的曝光提取。 PI将联合收割机美国大盆地奥陶纪和志留纪地层的地层学、沉积学和生物地层学研究，以开发层序模型;将沿着倾斜和走向断面追踪层序，以评估可用于识别层序边界的标准的变化。 这项工作不仅有助于了解大盆地的古生代历史，而且有助于建立深水碳酸盐岩单元的层序地层模式。 研究结果将在学术界和工业界都有用处。
