Acquisition of a Cryogenic Magnetometer for Paleomagnetic Research

该合同提供了南加州大学地质科学系购买用于古地磁研究的低温磁强计系统所需资金的一半。磁力计系统将用于岩石和岩石形成沉积物的磁化学研究项目，以确定其古地磁性质的来源以及这些性质如何随时间变化。使用新系统的其他项目包括研究上更新世期间地球磁场的古分子变化，美国西南部置换的地体的微板块构造研究，以及海洋和陆地沉积序列的磁性地层学测量。

This award provides one-half the funds required to acquire a cryogenic magnetometer system for paleomagnetic research in the Department of Geological Sciences at the University of Southern California. The magnetometer system will be used in research projects on the magnetochemical studies of rocks and rock-forming sediments to determine the source of their paleomagnetic properties and how these change with time. Other projects using the new system include studies of the paleosecular variations of the earth's magnetic field during the Plio-Pleistocene, microplate tectonic studies of displaced terranes in the southwestern U.S., and magnetostratigraphic measurements of marine and terrestrial sedimentation sequences.
