COLLABORATIVE RESEARCH: Fault Block Rotation and Intra- Continental Strain in the Northern Walker Lane, Basin and Range Province

小行星9405278 板块构造学的基本前提是，板块更像是刚性体，变形只发生在板块之间的边界上，这一前提在大陆内部被局部地违背了，正如广泛的扩散应变区的存在所证明的那样。 本研究板内应变集中在美国西部盆地山脉省的北方步行者巷。 先前的工作已经划定了断层边界块，确定了将产生有用的古地磁结果的单元，并记录了主要断层的滑动方向和方向，其中一些断层几乎相互正交。 这项工作将测试所确定的块体的垂直轴旋转，并将开发一个包括块体旋转在内的板内应变的运动学模型。 结果也将提供洞察陆内应变和板块边界相互作用之间的关系。

9405278 Ellis The basic premise of plate tectonics that plates more as rigid bodies with deformation occurring only at boundaries between plates is violated locally within continents, as demonstrated by the existence of broad zones of diffuse strain. This study intra-plate strain focuses on the northern Walker Lane in the Basin and Range province of the Western United States. Prior work has delineated fault-bounded blocks, identified units that will yield useful paleomagnetic results and documented the orientation and sense of slip an major faults, some of which are nearly orthogonal to each other. This work will test for vertical-axis rotations of the identified blocks and will develop a kinematic model of this example of intra-plate strain including block rotations. Results will also provide insight into the relationship between intracontinental strain nd plate-boundary interactions.
