Magnetic Petrology of the Lower Crust

小行星9316066 PI已经进行了下地壳岩石的磁性岩石学研究。 总的长期目标是通过对捕虏体、地壳横截面等的研究，增加我们对下地壳磁化的认识。他将分析来自会聚火山弧的捕虏体样品（阿留申群岛和日本群岛）和大陆裂谷带（格兰德河和西南极裂谷），研究了巴基斯坦科希斯坦弧下地壳岩石中角闪岩-麻粒岩相变质作用的影响。 样品将通过双重方法进行分析，包括磁性测量（初始磁化率、自然和饱和等温剩磁、居里点、磁滞等），辅以岩相学和微探针研究。 ****

9316066 Warner The PI has undertaken a study of the magnetic petrology of lower crustal rocks. The general long-term goal is to increase our understanding of lower crustal magnetization through the study of xenoliths, crustal cross sections, etc. He will analyze xenolith samples from convergent volcanic arcs (Aleutian and Japanese islands) and continental rift zones (Rio Grande and West Antarctic rifts), and investigate the effects of prograde (amphibolite to granulite facies) metamorphism in a traverse through lower crustal rocks exposed in the Kohistan arc, Pakistan. The samples will be analyzed via a dual approach involving magnetic property measurements (initial susceptibilities, natural and saturation isothermal remanence, Curie points, magnetic hysteresis, etc.), supplemented by petrographic and microprobe studies. ****
