MRI: Acquisition of Laboratory Equipment to Characterize Sediments and Soils for Paleoenvironmental Reconstructions

这笔重大研究仪器(MRI)赠款的GeissFunds将支持购买一台振动样品磁强计(VSM)，以确定地质样品中含铁矿物的磁滞参数，从而推断磁性颗粒分布。VSM将支持本科生机构三一学院物理系的研究和研究培训。对加拿大北冰洋湖泊沉积物和中西部古土壤的岩石磁学研究将有助于北美中大陆气候重建。

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.
