9316105 Saleeby The emplacement of large batholiths in compressional setting raises classic arguments about how space requirements are met, and the degree to which batholiths create their air space. This proposal will investigate the suggestion that a set of ductile shear zones from the southern Sierra Nevada batholith may represent deformation related to pluton emplacement dynamics which are linked kinematically to the Tehachapi-Rand thrust system. A test of this hypothesis involves establishing a firm physical and temporal link between the shear zones and the thrust system. Results will help resolve the local debate, and as the Sierra Nevada is commonly regarded as the type exposure of a batholithic belt, they will have importance generally.

小行星9316105 挤压环境中大型岩基的就位引发了关于如何满足空间要求以及岩基创造空气空间的程度的经典争论。 该提案将调查的建议，一组韧性剪切带，从南部的塞拉内华达州岩基可能代表变形有关的岩体侵位动力学的运动学连接到Tehachapi-Rand逆冲系统。 对这一假设的检验包括在剪切带和逆冲系统之间建立一个牢固的物理和时间联系。 结果将有助于解决当地的争论，而且由于内华达州山脉通常被认为是岩基带的典型出露，因此它们通常具有重要性。
