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.

9303966 Harris在这项合作研究中，PIS将制定和评估识别外架和斜率碳酸盐环境中地层序列的标准。 在这些设置中识别序列边界是有问题的，因为典型的边界标准不适用 - 不存在暴露事件，并且很难从露头规模暴露中提取层几何形状。 PIS将结合美国大盆地奥陶纪和志留纪地层的地层，沉积学和生物地层研究，以开发序列模型。这些序列将沿着倾角和罢工样带追溯，以评估可在识别序列边界中使用的标准的变化。 这项工作不仅有助于了解大盆地的古生代历史，还将有助于开发较深的水碳酸盐单元的序列地层模型。 结果将在学术界和行业中使用。
