0824559SmirnovThis grant supports acquisition of instrumentation to characterize the magnetic properties of rocks, minerals and sediments. A kappabridge equipped with variable sample temperature control capabilities (from -196°C to 700°C) for measuring anisotropy of magnetic susceptibility and bulk susceptibility in weak variable magnetic fields and a thermal demagnetizer equipped with a controlled atmosphere chamber and controlled field coil to permit measurement of paleointensity will be acquired by Michigan Technological University. The equipment will support PI research on the long-term evolution of Earth?s magnetic field in the Precambrian, studies of processes of acquisition and preservation of paleointensity signal in rocks, and studies of magnetism of sediments and soils for paleoclimatic and environmental applications. The equipment will support Ph.D. student research as well as undergraduate research projects both within MTU and also at nearby Lake Superior State University. Upgrade of the MTU paleomagnetism lab represents a significant research infrastructure enhancement for an isolated region of the upper Midwest U.S.

0824559 Smirnov该补助金支持购买仪器来表征岩石，矿物和沉积物的磁性。 密歇根理工大学将购置一台配备可变样品温度控制能力（从-196 ° C到700°C）的卡帕克布里奇，用于测量弱可变磁场中磁化率和体磁化率的各向异性，以及一台配备受控气氛室和受控磁场线圈的热脱磁器，用于测量古强度。 这些设备将支持PI对地球长期演化的研究。前寒武纪的地磁场、岩石中古强度信号的获取和保存过程的研究、沉积物和土壤磁性的古气候和环境应用研究。 该设备将支持博士学位。学生的研究以及本科生的研究项目都在MTU和附近的上级湖州立大学。 MTU古地磁实验室的升级代表了美国上中西部一个孤立地区的重大研究基础设施增强。
