In Northern Pakistan, a crustal section is preserved and exposed in Kohistan, NW Himilaya. The island arc section is unique in that a nearly complete cross-section of the earth's crust may be sampled there. The PI will study, by means of field and laboratory study, the rock magnetism of this section. The field and international travel expenses for this project have already been funded by the Smithsonian Institution (Excess Foreign Currency), and NSF funds are for the first year of laboratory study. This research will 1) add basic data on the physical properties of the middle and lower portions of the earth's crust, 2) provide constraining data on magnetization at depth, for improved geological interpretation of regional magnetic anomalies, 3) provide a suite of well-characterized samples for planned future petrophysical and experimental studies, and 4) foster an atmosphere of international cooperation.

在巴基斯坦北部，喜米拉雅西北部的科希斯坦保存着一段地壳，并被暴露出来。岛弧剖面的独特之处在于，在那里可以采样到几乎完整的地壳横截面。PI将通过野外和实验室研究的方式，研究这一段的岩石磁性。该项目的实地和国际旅行费用已经由史密森学会(超额外汇)提供资金，国家科学基金会的资金用于第一年的实验室研究。这项研究将1)增加关于地壳中下部物理性质的基本数据，2)提供关于深部磁化的约束性数据，以改进区域磁异常的地质解释，3)为计划中的未来岩石物理和实验研究提供一套特征良好的样品，以及4)促进国际合作的气氛。
