Collaborative Research: Thermal, Compositional and Dynamical Evolution of the Sub-continental Mantle During Orogeny

PIs提出了一项多学科研究，以建立受地震剪切波分裂和地质岩石数据集直接约束的次大陆上地幔动力、热和成分演化模型。该团队将开发并测试一个包含粘性产热的模型，试图调和看似矛盾的数据集，这些数据集表明次大陆地幔，特别是次大陆岩石圈，在造山运动期间异常热，但在造山运动期间没有被移除。＊＊＊

9713946 Silver The PIs propose a multi-disciplinary study to develop models of the dynamical, thermal and compositional evolution of the sub-continental upper mantle which are directly constrained by seismic shear wave splitting and geologic and petrologic data sets. The team will develop and test a model that incorporates viscous heat production in an attempt to reconcile seemingly conflicting data sets which suggest that sub-continental mantle, specifically sub-continental lithosphere, is anomalously hot during orogeny and yet is not removed during orogeny. ***
