The Continental Component Added to the Sedimentary Assemblages in the Canadian Cordillera: Nd Isotopic and other Geochemical Studies of Miogeoclinal Sequences

9315625 Patchett该项目将测量加拿大落基山脉微地斜中砂岩中的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时期供应的大陆物质的数量。碎屑锆石数据也将被用来确定远距离旅行的碎屑与近距离旅行的碎屑的相对数量。这一结果将为该地区今后的种源研究提供有用的基线。这一结果还将对该地区340 Ma大型地体的存在和造山带内个别地体的运动产生影响。这些发现将对其他造山带的构造地体研究具有广泛的应用价值。

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.
