9406586 Prave Building on a pilot project, PI and co-workers, including Paul Hoffman and members of the Namibian Geological Survey, will examine key strata from the late Proterozoic, a critical time in Earth and life history. Study will include sequence stratigraphy, structural geology, U-Pb geochronology, chemostratigraphy, and regional tectonics. Team will critically evaluate, chronometrically calibrate, and selectively refine the timing of Neoproterozoic isotopic excursions and glaciations, as well as the timing and kinematics of continental breakup and assembly of southern Gondwanaland.

在一个试点项目的基础上，PI和同事们，包括Paul Hoffman和纳米比亚地质调查局的成员，将研究晚元古代的关键地层，这是地球和生命史上的关键时期。研究内容包括层序地层学、构造地质学、铀铅年代学、化学地层学和区域构造学。团队将对新元古代同位素漂移和冰川作用的时间进行批判性的评估、时间上的校准，并有选择地完善时间，以及冈瓦纳大陆南部大陆分裂和组装的时间和运动学。
