Upgrade of University of New Hampshire Paleomagnetism Laboratory

[841586]这项拨款支持新罕布什尔大学地球科学系购买新一代2g超导岩石磁力计，该磁力计带有不需要液体He的脉冲管制冷机，磁感应计和岩心钻。SRM和其他古地磁设备将支持PI研究哺乳动物在气候和构造变化下的进化。PI研究依赖于在空间分布的岩心中极性反转的磁地层对比，有些岩心有脊椎动物化石剖面，有些没有，有些是大陆的，有些是海洋的。岩心中记录的环境代用物可以推断区域和/或全球气候变化和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的同向性研究、喜马拉雅隆起对生物进化的影响研究都将受益于SRM。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.
