9406917 McCaffrey During oblique plate convergence, the faults that take up the strain can more oblique to the suture in sympathy to the oblique convergence, or they can be partitioned with some being orthogonal thrusts and others orogen-parallel strike-slip faults. This project will extend prior work on the partitioning of oblique subduction in oceanic settings to continental setting. factors that control the style of deformation associated with oblique plate convergence will be constrained by conducting three-dimensional finite-element numerical experiments. Results are expected to shed light on how strain is partitioned in oblique continental plate convergent situations.

小行星9406917 在斜向板块会聚过程中，承受应变的断层可以与斜向会聚一致地向缝合线倾斜，也可以划分为正交逆冲断层和平行造山带的走滑断层。 该项目将把以前关于大洋斜俯冲划分为大陆斜俯冲的工作扩大。 控制与斜板会聚相关的变形类型的因素将通过进行三维有限元数值实验来约束。 预计结果将揭示如何在倾斜的大陆板块收敛的情况下，应变的划分。
