中文摘要

9526803格雷兹纳独立岩墙群是加利福尼亚州的一个重要标志，它跨越了几个重要的岩石圈和构造边界。直到最近，它的时代还被认为是最晚的侏罗纪，然而许多脉岩被证明是白垩纪的，因此它们是在内华达山脉的左旋剪切变形期间侵位的，而不是在那次变形之前。这个项目将解决岩群中岩脉的年龄问题，并试图了解它们在同步变形事件中所起的运动学作用。结果应该有助于阐明它们起源的时代和构造条件，从而提高它们作为区域标志的实用性。
英文摘要
9526803 Glazner The Independence Dike Swarm is an important marker feature in California that crosses several important lithospheric and structural boundaries. Until recently its age was accepted as latest Jurassic, however many of the dikes have been shown to be cretaceous, and thus were emplaced during sinistral shear deformation in the Sierra Nevada rather than prior to that deformation. This project will address the ages of the dikes in the swarm and attempt to understand the kinematic role they played in the synchronous deformation event. Results should help clarify the age and tectonic conditions of their origins, thus improving their utility as regional markers.
