0087556HarlanThis grant provides support to acquire alternating field, thermal demagnetization, and susceptibility (Spinner Kappabridge) equipment and magnetic shielding to establish a fully functional paleomagnetic laboratory in the Geography and Earth Systems Science Department of George Mason University. The paleomagnetic equipment will complement paleomagnetic instruments and equipment (spinner magnetometer, impulse magnetizer, portable drill and orientation equipment) already acquired by GMU. The paleomagnetic equipment will be utilized primarily by the principal investigator, Stephen S. Harlan and his students, but will also be available for use by individuals from universities and government agencies in the regional Virginia-Washington, D.C.-Maryland area. The Spinner Kappabridge, in particular, will be unique to this region. Current research projects by the principal investigator include the paleomagnetism and geochronology of Proterozoic rocks in the western U.S. and Canada, the timing of fold and thrust belt deformation in the Cordilleran orogenic belt, the nature and origin of magnetic phases in modern and ancient soils and their parent materials, and paleomagnetic, rock magnetic, and magnetic fabric studies of silicic volcanic rocks in the eastern Snake River Plain and Yellowstone National Park. Support for the acquisition of this equipment is shared by the NSF Earth Sciences Instrumentation and Facilities Program (EAR/IF) and by George Mason University.***

0087556哈兰这笔赠款提供支持，以获得交变场，热退磁，和磁化率（旋转Kappabridge）设备和磁屏蔽，以建立一个功能齐全的古地磁实验室在地理和地球系统科学系的乔治梅森大学。这些古地磁设备将补充GMU已经购置的古地磁仪器和设备（旋转磁力计、脉冲磁化器、便携式钻机和定向设备）。古地磁设备将主要由首席研究员斯蒂芬·S·哈兰和他的学生，但也将提供给个人使用的大学和政府机构在该地区的哥伦比亚特区华盛顿-马里兰州地区。特别是Spinner Kappabridge将是该地区的独特之处。首席研究员目前的研究项目包括美国西部和加拿大元古代岩石的古地磁学和地质年代学，科迪勒拉造山带褶皱和冲断带变形的时间，现代和古代土壤及其母质中磁相的性质和起源，以及古地磁，岩石磁性，对蛇河平原东部和黄石国家公园的火山岩进行了磁组构研究。美国国家科学基金会地球科学仪器和设施计划（NSF/IF）和乔治梅森大学（George Mason University）共同支持购买该设备。
