Collaborative Research: Cenozoic Exhumation and Tilting in the Southern Coast Mountains

0001223 Farley0001147 Rusmore地形、构造、剥露和气候之间的关系是复杂的，识别和分离这些因素是困难的。 不列颠哥伦比亚省的海岸山脉是一个单一的地形范围，北部为转换边缘，南部为会聚边缘，但初步数据表明，新生代剥露历史沿着该范围的长度是均匀的。 这一情况为评价控制该山脉形成和演化的主导机制提供了机会。 这项工作包括对造山带南部进行综合的低温地质年代学、古地磁学和构造研究，并与北部最近的类似工作进行比较。 结果有望揭示在这个造山带，这应该有助于了解一般的山脉形成的地形控制因素。

0001223 Farley0001147 RusmoreThe relationships between topography, tectonics, exhumation and climate are complex, and identifying and separating the factors is difficult. The Coast Mountains of British Columbia are a single physiographic range bordered by a transform margin in the north and a convergent margin in the south, yet preliminary data indicates that the Cenozoic exhumation history along the length of the range was uniform. This circumstance provides an opportunity to evaluate the dominant mechanism controlling the formation and evolution of this mountain range. The work involves an integrated low-temperature geochronologic, paleomagnetic and structural study across the southern part of the orogen and comparison to similar recent work to the north. Results are expected to shed light on the factors controlling topography in this orogen, which should help understand the formation of mountain ranges in general.
