Collaborative Research: Lower-Middle Cambrian of Avalon and Morocco: Biostratigraphy, Geochronology, and Dynamic Stratigraphy

9405114着陆PI和合作者将开发新的生物地层学和地质年代学基础的阿瓦隆和摩洛哥的下-中寒武统的对比。对阿瓦隆序列的小壳化石的详细研究，结合高精度的地质年代学，将为地球生命进化的这一重要时期提供一个显着精确的时间尺度。摩洛哥序列的研究将允许相关性，并允许在时间尺度上扩展研究。这项工作也将有助于了解这些寒武纪地台的构造历史。

9405114 Landing PIs and collaborators will develop new biostratigraphic and geochronologic bases for correlation of the Lower-Middle Cambrian of Avalon and Morocco. Detailed work on the small shelly fossils of the Avalon sequence, combined with high-precision geochronology, will provide a significantly refined time scale for this important time in evolution of life on Earth. Study of Moroccan sequence will permit correlation, and allow extension of the study in the time scale. Work will also contribute to understanding the tectonic history of these Cambrian platforms.
