9807021 Banerjee Funds awarded by NSF to the Institute for Rock Magnetism (IRM) will be matched (50% basis) by the University of Minnesota to acquire two new instruments, a Magnetic Property Measurement System (MPMS) and an Alternating Field Demagnetizer, and upgrade two current instruments, a Mossbauer Spectrometer and an Alternating Gradient Force Magnetometer (AGFM, also known as "Micromag"). The IRM is a national facility for advanced in-house and extramural research in fundamental rock magnetism and its applications to research in tectonics, stratigraphy, marine geology and geophysics, past climatic and environmental change and bio-mineralization. The new equipment will result in a significant increase in the capability to identify and quantify very low concentrations (100ppm or greater) of the oxides, hydroxides, carbonates and sulfides of iron present in continental and marine sediments. These minerals serve as sensitve indicators of geological processes icluding changes in the geomagnetic field, plate tectonic motions, microbial mineralization and climatic change. ***

小行星9807021 美国国家科学基金会授予岩石磁性研究所（Institute for Rock Magnetism）的资金将由明尼苏达大学（University of Minnesota）提供（50%的基础），用于购买两台新仪器，一台磁性能测量系统（MPMS）和一台交变场退磁器，并升级两台现有仪器，一台穆斯堡尔谱仪和一台交变梯度力磁力计（AGFM，也称为“Micromag”）。该中心是一个国家设施，用于基础岩石磁性及其在构造学、地层学、海洋地质学和地球物理学、过去气候和环境变化以及生物矿化研究中的应用方面的先进内部和外部研究。 新设备将大大提高识别和量化大陆和海洋沉积物中极低浓度（100 ppm或更高）铁的氧化物、氢氧化物、碳酸盐和硫化物的能力。 这些矿物是地质作用的敏感指标，包括地磁场变化、板块构造运动、微生物矿化和气候变化。 ***
