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.

这项工作涉及数值实验，将非常年轻的海洋岩石圈的屈服强度的特点，通过约束的数值模型，以配合现有的观测。戈尔达海岭的数据将用于约束岩石圈的相对强度小于2 Ma和4-7 Ma的年龄。这些模型还将测试控制脊变换和重叠扩展中心几何形状的物理因素。最后，将模拟近洋脊海山施加的载荷。
