COLLABORATIVE RESEARCH: Paleogene Collision and Obduction of the Far-Traveled Olyutorsky Island Arc, Northern Kamchatka, Russian Far East

岛弧/大陆弧碰撞通常被用来解释古代山带的造山变形，但这种类型的碰撞在现代海洋中没有很好的代表。耶鲁大学和联合学院的工作人员合作的这个项目，将研究一个内部汇聚的大陆弧和一个奇特的晚白垩世岛弧（Olyutorsky terrane）之间暴露良好的缝合线（冲力），以帮助解决在这种情况下预期的运动学问题，这种缝合线后来的变形看起来很小。结果应该提供一个相对清晰的数据集，可以用来测试白垩纪晚期北太平洋板块演化的几个模型，以及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.
