9706391 Kepezhinskas Paleomagnetic data has proven key to the interpretation of terrane migration and accretion along several convergent continental margins, with Alaska being as notable example. Existing data suggests that the Kamchatka Peninsula, Russia may also be a college of accreted allochthonous terranes, but the geologic and paleomagnetic data base is not extensive, and the area is difficult logistically. This project will attempt to place the paleomagnetic and geologic data on a firmer base so that plate kinematic models related to terrane emplacement can be formulated and tested. Results will increase knowledge about terranes in Kamchatka and provide the basis for understanding displacement histories of northern Pacific terranes.

小行星9706391 古地磁数据已被证明是解释沿沿着几个会聚大陆边缘的岩石迁移和增生的关键，阿拉斯加是一个值得注意的例子。 现有资料表明，俄罗斯堪察加半岛也可能是一个增生的外来岩群，但地质和古地磁数据库并不广泛，该地区是难以后勤。 该项目将试图把古地磁和地质数据放在一个更坚实的基础上，以便能够制定和测试与地幔侵位有关的板块运动学模型。 研究结果将增加对堪察加半岛海扇的认识，并为了解北方太平洋海扇的位移历史提供依据。
