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 Duebendorfer，Ernest M.A中元古代岩浆带从加州延伸到拉布拉多，但其构造意义是有争议的，主要是因为缺乏可用于推断构造环境的区域广泛的普遍组构结构。 本项目通过对南怀俄明州1.4Ga剪切带中同运动矿物的填图、构造分析和U-Pb年代学的综合研究来解决这一问题。 研究结果将有助于解决这一构造幕的各种挤压或伸展模式。
