9315625 Patchett This project will measure Nd isotopes, REE and other trace elements in sandstone from the miogeocline of the Canadian Rocky Mountains in order to quantify the amount of continental material supplied during the lifetime of the Canadian Cordillera. Detrital zircon data will also be used to determine the relative amounts of far-traveled versus near-travelled detritus. The results will give a useful baseline for future provenance studies in the region. Results will also have implications for the existence of a large, 340 Ma terrane in the region and the movement of individual terranes within the orogen. These findings will have broad application to the study of tectonic terranes in other orogenic belts.

9315625 Patchett 该项目将测量加拿大落基山脉缓地斜层砂岩中的 Nd 同位素、稀土元素和其他微量元素，以量化加拿大科迪勒拉山脉生存期间供应的大陆物质数量。 碎屑锆石数据还将用于确定远行和近行碎屑的相对数量。 研究结果将为该地区未来的起源研究提供有用的基线。 结果还将对该地区是否存在大型 340 Ma 地体以及造山带内各个地体的运动产生影响。 这些发现将广泛应用于其他造山带构造地体的研究。
