Acquisition of Equipment to Establish a Paleomagnetic Laboratory at George Mason University

0087556哈兰这笔赠款提供支持，以获得交变磁场、热去磁和磁化率(旋转卡普布里奇)设备和磁屏蔽，以在乔治梅森大学地理和地球系统科学系建立一个功能齐全的古地磁实验室。古地磁设备将补充GMU已经获得的古地磁仪器和设备(旋转磁力仪、脉冲磁化器、便携式钻探和定位设备)。古地磁设备将主要由首席研究员斯蒂芬·S·哈伦和他的学生使用，但也将供弗吉尼亚-华盛顿特区-马里兰州地区的大学和政府机构的个人使用。特别是卡普布里奇旋转器，将是该地区独一无二的。首席调查员目前的研究项目包括美国西部和加拿大元古界岩石的古地磁和年代学，科迪勒山造山带褶皱和逆冲带变形的时间，现代和古代土壤及其母质中磁性相的性质和来源，以及东部蛇河平原和黄石国家公园硅质火山岩的古地磁、岩石磁性和磁性组构研究。美国国家科学基金会地球科学仪器和设施计划(EAR/IF)和乔治梅森大学共享对该设备采购的支持。

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.***
