COLLABORATIVE RESEARCH: RUI: Cenozoic Collision of the Olyutorsky Volcanic Arc, Northern Kamchatka, Russian Far East

岛弧/陆弧碰撞通常被用来解释古山带的造山变形，但这种碰撞类型在现代海洋中并没有得到很好的代表。耶鲁大学和联合学院的这项合作项目将检查内侧会聚大陆弧和奇特的晚白垩世岛弧(Olyutorsky地体)之间暴露良好的缝合线(推力)，以帮助解决在这种情况下预期的运动学，这种缝合线后来的变形似乎最小。结果应该提供一个相对清晰的数据集，可以用来检验北太平洋晚白垩世板块演化的几个模型，并提供一个相对现代的大陆弧/岛弧碰撞的例子。

Island arc/continental arc collisions are commonly invoked to explain orogenic deformations in ancient mountain belts, but this type of collision is not well represented in the modern oceans. This collaborative project between workers at Yale University and Union College, will examine a well-exposed suture (thrust) between an inboard convergent continental arc and an exotic late cretaceous island arc (Olyutorsky terrane) to help resolve the kinematics expected in such situations, later deformations of this suture appears minimal. Results should provide a relatively clear data set that can be used to test several models for the evolution of plates in the north Pacific during the late Cretaceous as well as providing a relatively modern example of a continental arc/island arc collision.
