Regional Batholithic Tectonics of an Exposed Cross-Section of Young (~100 Ma) Continental Crust, Southern Sierra Nevada, California

与俯冲构造有关的大岩基的发育在地壳成因中具有相当大的意义。先前在内华达山脉的研究表明，目前的侵蚀面斜切了一个30公里深的剖面，因此提供了一个机会来建立一个模型，同时研究同一块以岩基为主的地壳的浅层和深层部分。这项工作涉及构造、岩石学和地质年代学研究，旨在了解大约1亿年前基岩的发展情况。研究结果将完善对加利福尼亚俯冲相关深部成矿作用的认识，也适用于一般的岩基发育模式。

The development of large batholiths associated with subduction tectonics is of considerable interest in crustal genesis. Prior work in the Sierra Nevada has indicated that the present erosion surface cuts obliquely through a 30 kilometer depth section, thus offering an opportunity to develop a model of both shallow and deep portions of the same batholith-dominated crust. The work involves structural, petrographic and geochronological studies aimed at understanding the development of the batholith as of approximately 100 million years ago. Results will refine understanding of subduction-related plutonism in California, which should also apply to general models of batholith development.
