9418586 Chamberlain The assembly of cratons involves formation of crustal-scale boundaries as disparate crustal blocks collide and amalogmate. Understanding of these boundaries in younger rocks is aided by relatively shallow levels of exposure and relatively clear lithologic and temporal differences. However, aspects of precambrian terrane boundaries remain problematic due in part to deep levels of exposure and reliance an isotopic data for terrane discrimination. This collaborative project will employ a variety of techniques and study one Precambrian boundary (Mojave and Yavapai) in considerable detail, with the goal of formulating a tectonic model for development of the zone that honors all geologic constraints. Results will lead to increased understanding of crustal boundaries in deeply eroded ancient accreted terranes.

小行星9418586 当不同的地壳块体相互碰撞和同化时，板块的聚集涉及到地壳尺度边界的形成。 相对浅的暴露水平和相对清晰的岩性和时间差异有助于了解较年轻岩石中的这些边界。 然而，前寒武纪碳酸盐岩边界的各个方面仍然存在问题，部分原因是深层次的暴露和对碳酸盐岩同位素数据的依赖。 这个合作项目将采用各种技术，并相当详细地研究一个前寒武纪边界（莫哈韦和亚瓦派），目标是制定一个构造模型，用于开发尊重所有地质约束的区域。 研究结果将有助于加深对深侵蚀古加积岩中地壳边界的理解。
