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.

0841586Clyde 这项赠款支持新罕布什尔大学地球科学系购买新一代 2-G 超导岩石磁力计，该磁力计配有脉冲管制冷机，不需要液氦、磁敏感计和岩心钻机。 SRM 和其他古地磁设备将支持 PI 研究哺乳动物因气候和构造变化而进化的情况。 PI研究依赖于跨空间分布的核心的极性反转的磁地层相关性，一些核心含有脊椎动物化石，另一些没有，一些是大陆性的，另一些是海洋性的。 岩心中记录的环境代理可以推断区域和/或全球气候变化以及相关构造对生物进化的影响。 大角盆地古新世/始新世化石记录的北美大陆哺乳动物进化研究，北美和亚洲古新世/始新世陆地哺乳动物进化同步性研究，喜马拉雅隆升对人类的影响研究生物进化都将受益于所要求的 SRM。 PI 研究将涉及重要的美国学术和国外合作以及学生的参与。
