Collaborative Research: Geodynamics of the Eastern California Shear Zone

0003396弗隆0003740迪克森东加州剪切带是太平洋-北美板块边界的主要组成部分，沿着该边界容纳了20-25%的总应变，圣安德烈亚斯系统和剪切带之间几乎没有变形。 圣安德烈亚斯系统传统上被认为是太平洋板块和北美板块之间的板块边界，但东加州剪切带的性质是有争议的，有各种假设，它完全类似于板块边界，以反映北美板块边缘的局部影响。 该项目旨在将新的GPS观测结果和地球动力学建模结合起来，以测试这些不同的假设。联合收割机。 结果有望更好地阐明东加州剪切带在太平洋板块-北美板块构造中的作用。

0003396Furlong0003740DixonThe Eastern California Shear Zone serves as a major component of the Pacific-North American plate boundary, accommodating 20-25% of the total strain along this boundary, with little deformation occurring between the San Andreas system and the shear zone. The San Andreas system is traditionally considered to mark the plate boundary between the Pacific plate and the North American plate, but the nature of the Eastern California Shear Zone is controversial, with hypotheses varying between it being completely analogous to a plate boundary to reflecting local effects within the edge of the North American plate. This project intends to combine new GPS observations and geodynamical modeling to test these various hypotheses. Results are expected to better clarify the role of the Eastern California Shear Zone in Pacific plate - North American plate tectonics.
