0527215DriscollAbstractThe PI will attempt a series of numerical experiments to examine the depth-dependent extension and consequent subsidence of the lithosphere during late stage of continental rifting and early seafloor spreading. Lithospheric thinning, margin breakup and seafloor spreading will be modeled. The PI will explore three alternative hypotheses put forward to explain depth-dependent extension.The work could lead to better insight about how hydrocarbons accumulate and evolve on divergent margins. Scripps Institutions aquarium outreach for K-12 students and science interest in the community and the support of a female co-PI as a post-doc are other broader impacts of this project.

PI将尝试一系列数值实验，以研究大陆裂谷晚期和海底早期扩张过程中岩石圈随深度变化的伸展和随后的下沉。将模拟岩石圈变薄、边缘破裂和海底扩张。PI将探索提出的三种解释深度相关伸展的替代假设。这项工作可能会更好地洞察碳氢化合物如何在不同的边缘聚集和演化。斯克里普斯机构、对K-12学生的水族馆推广活动、对社区的科学兴趣以及女性合作者作为博士后的支持，都是该项目的其他更广泛的影响。
