Upgrade of University of New Hampshire Paleomagnetism Laboratory

0841586Clyde这笔赠款支持新一代具有脉冲管制冷机的2-G超导岩石磁强计的采购，该设备不需要液体氦、磁化率计和岩心钻头，由新汉普郡大学地球科学系提供。SRM和其他古地磁设备将支持PI对哺乳动物随气候和构造变化而进化的研究。PI研究依赖于空间分布的岩心的极性反转的磁性地层学对比，其中一些岩心含有脊椎动物化石段，另一些没有，一些是大陆的，另一些是海洋的。记录在岩心中的环境指标可以推断区域和/或全球气候变化及相关构造对生物进化的影响。大角盆地古新世/始新世化石中记录的北美大陆哺乳动物进化研究、北美与亚洲之间古新世/始新世陆地哺乳动物进化同步性研究以及喜马拉雅隆起对生物进化的影响研究都将受益于所要求的可持续土地管理。PI研究将涉及重要的美国学术和外国合作以及学生的参与。

0841586ClydeThis grant supports acquisition of a new generation 2-G superconducting rock magnetometer with pulsed tube cryocooler that does not require liquid He, a magnetic susceptometer, and core drill by the Department of Earth Sciences at the University of New Hampshire. The SRM and other paleomagnetic equipment will support PI research on the evolution of mammals in response to changes in climate and tectonics. PI research relies on magnetostratigraphic correlation of polarity reversals across spatially distributed cores, some with vertebrate fossil bearing sections, others without, some continental, others marine. Environmental proxies recorded in cores allow inferences regarding the effects of regional and/or global climate change and related tectonics on biological evolution. Studies of the evolution of mammals on the North American continent as recorded in Paleocene/Eocene fossils of the Big Horn Basin, studies of the synchroneity of Paleocene/Eocene land mammal evolution between North America and Asia, and studies of the effects of Himalayan uplift on biologic evolution will all benefit from the requested SRM. PI studies will involve significant U.S. academic and foreign collaborations and student involvement.
