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型岩基的发展对地壳成因有相当大的兴趣。内华达山脉先前的工作表明，目前的侵蚀面斜切30公里深的部分，从而提供了一个机会，建立同一岩基主导的地壳的浅部和深部的模型。这项工作包括结构、岩石学和地质年代学研究，旨在了解大约1亿年前岩基的发展。这些结果将加深对加州俯冲相关深成学说的理解，这也应该适用于岩基发育的一般模型。

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.
