This study is of the way in which magnetic mineralogy and petrology vary across metamophic aureoles in basic and ultrabasic rocks in Washington State and on Vancouver Island. It will test models predicting the appearance and disappearance of magnetic phases during prograde metamorphic reactions, to characterize the induced and remanent magnetic properties associated with these phases, and to extrapolate the results to deeper crustal levels.

这项研究是磁性矿物学和岩石学在华盛顿州和温哥华岛的基性和超基性岩石的变质光圈中变化的方式。它将测试预测在渐进变质反应中磁相出现和消失的模型，以表征与这些相相关的诱导和剩余磁性，并将结果推断到更深的地壳水平。
