9902937FurlongIn actively subducting plate boundaries, triple junctions migrate as a function of convergence obliquity, which is seldom orthogonal. Recent geodynamic models predict a complex crustal response to triple junction passage including initial thickening followed by thinning within a 5 m.y. time frame following passage. These geodynamic model results have specific geomorphological predictions, and geomorphological data from a region recently experiencing passage of a triple junction should provide a test of the geodynamic model. This project will gather geomorphological data along the northern California coast where the Mendocino triple junction has been migrating northward along the coast. Results will likely provide a test of the geodynamic model which should have broad applicability and also increase knowledge about the Mendocino triple junction area of northern California.

在活跃的俯冲板块边界中，三个结点作为会聚倾角的函数迁移，这很少是垂直的。最近的地球动力学模型预测了一个复杂的地壳对三重连接通道的响应，包括最初的增厚，然后在5英里内变薄。通过之后的时间范围。这些地球动力学模型的结果具有特定的地貌预测，最近经历了三重结点的地区的地貌数据应该提供了对地球动力学模型的检验。该项目将收集加利福尼亚州北部海岸的地貌数据，门多西诺三重结点一直在沿海岸向北迁移。结果可能会为地球动力学模型提供测试，该模型应该具有广泛的适用性，并增加对加利福尼亚州北部门多西诺三交界处地区的了解。
