0001144 Chamberlain, Kevin R.0001241 Duebendorfer, Ernest M.A mesoproterozoic magmatic belt extends from California to Labrador, yet its tectonic significance is controversial, largely because of the absence of regionally extensive structures of pervasive fabrics that can be used to deduce tectonic setting. This project addresses this problem by an integrated program of mapping, structural analysis and U-Pb geochronology on synkinematic minerals from 1.4 Ga shear zones in Southern Wyoming. Results are expected to help resolve various compressional or extensional models for this tectonic episode.

0001144 Chamberlain, Kevin R.0001241 dubenendorfer, Ernest m .中元古代岩浆带从加利福尼亚延伸至拉布拉多，但其构造意义存在争议，主要是因为缺乏可用于推断构造背景的普遍结构的区域性广泛构造。该项目通过对怀俄明州南部1.4 Ga剪切带的同动矿物进行制图、结构分析和U-Pb地质年代学的综合项目来解决这个问题。结果有望帮助解决该构造事件的各种挤压或伸展模式。
