Transpression: Consequences for Pluton Emplacement in the Sierra Nevada

主要的山系在一定程度上是俯冲带板块相互作用带来的大量岩浆注入的结果。地质学中的一个经典问题是“空间问题”，即大量(数千立方英里)的岩浆是如何在地壳中物理容纳的，即所需的空间是如何创造的。研究人员最近提出了一个力学模型，解释了如何通过P-断裂来创造岩浆的空间。该项目将通过收集现场数据和进行计算机实验来验证这一假设。该项目还有可能提供对矿床构造控制的洞察，最终可能导致改进勘探战略。

Major mountain systems are in part the result of large infusions of magma bought on by the interaction of plates at subduction zones. A classic problem in geology has been the "room problem", namely how are large volumes (thousands of cubic miles) of magma physically accommodated in the earth's crust, i.e., how is the requisit space created. The investigators have recently proposed a mechanical model that explains how space for magmas can be created via P- fractures. This project will test this hypothesis by gathering field data and by conducting computer experiments. This project also has the potential of providing insights into the structural controls on ore deposits that may lead ultimately to improved strategies for exploration.
