Testing of Possible Direct Relationships between Late Cretaceous Dextral Shearing of the Sierra Nevada Batholith & Large Magnitude Thrust Faulting of S. California Regio

在挤压环境中，大型基岩的就位引发了关于如何满足空间需求以及基岩在多大程度上创造空气空间的经典争论。本提案将研究一组来自内华达山脉南部基底的韧性剪切带可能代表与与特哈查皮-兰德逆冲系统运动学相关的岩体侵位动力学相关的变形。对这一假设的检验包括在剪切带和逆冲系统之间建立牢固的物理和时间联系。结果将有助于解决当地的争论，由于内华达山脉通常被认为是一个底石器时代带的类型暴露，它们将具有普遍的重要性。

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.
