Finite-Element Modeling of Deformation of Young Oceanic Lithosphere

这项工作包括数值实验，通过约束数值模型与现有观测结果相匹配，来表征非常年轻的大洋岩石圈的屈服强度。来自戈尔达岭的数据将被用来限制岩石圈的相对强度小于2 Ma和4-7 Ma。这些模型还将测试控制脊形变换和重叠扩展中心几何形状的物理因素。最后，将对近海脊海山施加的载荷进行建模。

This work involves numerical experiments that will characterize the yield strength of very young oceanic lithosphere by constraining the numerical models to match existing observations. Data from the Gorda Ridge will be used to constrain the relative strengths of lithosphere less than 2 Ma old, and 4-7 Ma old. The models will also test the physical factors controlling ridge-transform and overlapping spreading center geometry. Finally, the loading imposed by near-ridge seamounts will be modeled.
