This award provides for two-thirds of the funds required to acquire a Kappabridge magnetometer,reputed to be the most sensitive, off-the-shelf system for measuring anisotropy of magnetic susceptibility (AMS) over short time periods (minutes). The university is committed to provide the additional funds to make this acquisition possible. The instrument will be used by the PI and his students in a study designed to test the effect of progressive metamorphism on the development of AMS in rocks containing paramagnetic minerals and essentially no ferromagnetic minerals. Certain types of AMS data are reported to be helpful in interpreting the strain state and strain history of deformed rocks.This kind of information is necessary to reconstruct the nature and magnitude of orogenic (mountain building) processes. Several other faculty and students from nearby colleges and universities also intend to use this instrument.

该合同提供了购买卡普布里奇磁强计所需资金的三分之二，卡普布里奇磁强计被认为是在短时间(分钟)内测量磁化率(AMS)各向异性的最灵敏的现成系统。该大学承诺提供额外资金，使这一收购成为可能。PI和他的学生将在一项研究中使用该仪器，该研究旨在测试递进变质作用对含有顺磁性矿物和基本上不含铁磁性矿物的岩石中AMS发展的影响。据报道，某些类型的AMS数据有助于解释变形岩石的应变状态和应变历史。这种信息对于重建造山(造山)过程的性质和规模是必要的。来自附近高校的其他几名教职员工和学生也打算使用这种仪器。
