The Institute for Rock Magnetism (IRM) at the University of Minnesota will conduct research on rock magnetism as a multi-user facility for the next five years. They will operate a full suite of sensitive instrumentation for detailed study of magnetic properties of natural materials, provide for training of graduate and postgraduate students in state-of-the-art paleomagnetic analysis techniques and facilitate international collaborations through the Visiting Fellows program and a biennial conference series. Paleomagnetic and geomagnetic research crosscuts many of the disciplinary areas of the Earth Sciences Division.Research facilitated by the analytical and technical capabilities of the IRM includes high resolution studies of variability in the intensity of the Earth's magnetic field in order to elucidate fundamental questions surrounding the origin of the geodynamo, characterization of the properties of microbial nanophase magnetic minerals, and the origin of magnetization in minerals and the behavior of magnetic minerals in response to environmental perturbations in temperature and applied magnetic fields. The scale of investigations extends from bacterial magnetic particles and environmental reconstructions to plate tectonic reconstructions and magnetic mapping of other planets.

明尼苏达大学岩石磁性研究所（IRM）将在未来五年内作为多用户设施进行岩石磁性研究。 他们将操作一套完整的敏感仪器，用于详细研究天然材料的磁性，为研究生和研究生提供最先进的古地磁分析技术培训，并通过访问学者计划和两年一度的会议系列促进国际合作。古地磁学和地磁学研究贯穿地球科学司的许多学科领域，地球科学研究所的分析和技术能力促进了研究，包括对地球磁场强度变化的高分辨率研究，以阐明围绕地球发电机起源的基本问题，微生物纳米相磁性矿物的特性，以及矿物磁化的起源和磁性矿物对温度和外加磁场环境扰动的响应行为。调查的规模从细菌磁性颗粒和环境重建到板块构造重建和其他行星的磁性测绘。
