0923043GeissFunds from this Major Research Instrumentation (MRI) grant will support the acquisition of a vibrating sample magnetometer (VSM) to determine magnetic hysteresis parameters of iron-bearing minerals in geological samples and thereby infer magnetic grain-size distribution. The VSM will support research and research training in the Department of Physics at Trinity College, an undergraduate institution. North American midcontinent climate reconstructions will be aided by rock magnetic investigations of Canadian Arctic lake sediments and Midwestern paleosols.

0923043GeissFunds从这个重大研究仪器（MRI）补助金将支持购买振动样品磁强计（VSM），以确定磁滞参数的含铁矿物在地质样品，从而推断磁性粒度分布。 VSM将支持本科院校Trinity College物理系的研究和研究培训。 北美大陆中部气候重建将得到加拿大北极湖泊沉积物和中西部古土壤的岩石磁学调查的帮助。
