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.

岛弧/大陆弧碰撞通常被用来解释古代山脉带的造山变形，但这种类型的碰撞在现代海洋中并没有很好的代表性。 耶鲁大学和联合学院的工作人员之间的这个合作项目将检查内侧会聚大陆弧和异国情调的晚白垩世岛弧（Olyutorsky）之间的暴露良好的缝合线（逆冲断层），以帮助解决在这种情况下预期的运动学，该缝合线的后期变形似乎很小。 结果应该提供一个相对清晰的数据集，可用于测试几个模型在北太平洋板块的演化在白垩纪晚期，以及提供一个相对现代的例子大陆弧/岛弧碰撞。
