Collaborative Research: Tertiary Tilting andExhumation, Coast Mountains (RUI)

小行星9805124 不列颠哥伦比亚省的海岸山脉是两个科学问题的核心，这两个问题是关于倾斜会聚边缘如何运作的。 这些因素包括火山岩沿造山带迁移的程度和速度以及附属块体的抬升和侵蚀。 古地磁结果表明，长距离沿造山带运输是模糊的，因为这些数据所使用的岩体可能已经倾斜。 该项目的一部分将使用低温封闭老化方法的新技术测试倾斜。 这些和相关的结构数据也将解决的数量和速度的构造隆起，在这个几乎走滑端部成员的斜碰撞的情况。 这项工作将受益于并补充沿着ACCRETE样带的地质和地球物理研究。 研究结果将有助于解决斜碰撞引起的北美西海岸岩石沿着向北迁移的程度和抬升的问题。

9805124 Rusmore The Coast Mountains of British Columbia are central to two scientific questions concerning how an oblique convergent margin operates. These involve the extent and rate of along-orogen transport of terranes and uplift and erosion of attached blocks. Paleomagnetic results indicating long-distance along-orogen transport are ambiguous because the plutons that were used for these data may have been tilted. Part of this project will test for tilting using new techniques of low-temperature closure age methods. These and associated structural data will also address the amount and rate of tectonic uplift in this nearly strike-slip end member of oblique collisional circumstances. The work will benefit from and will complement geological and geophysical study along the ACCRETE transect. Results are expected to help resolve the degree of northward transport of terranes along the western coast of North America and the uplift associated with oblique collision.
