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

与俯冲作用有关的大型岩基的发育 大地构造学在地壳成因方面具有相当大的意义。 之前 在内华达州的研究表明， 表面倾斜地穿过30公里深的部分， 提供了一个机会来开发一个模型， 同一个岩基为主的地壳的部分。 工作涉及 结构、岩石学和年代学研究， 了解岩基的发展， 一亿年前。 结果将使人们更好地理解 在加州的俯冲相关的深成作用，这也应该适用于 到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.
