Acquisition of a Vibrating Sample Magnetometer for the Rock Magnetism Laboratory at Southern Illinois University

0521558 FerreThis重大研究仪器（MRI）计划拨款支持南伊利诺伊大学地质系购买普林斯顿测量3900-04振动样品磁强计（VSM）。 PI Eric Ferre将使用VSM开发测量高场磁化率（HFAMS）的方法，并培训学生进行磁性测量。 HFAMS方法可以分辨出顺磁源和铁磁源对磁化率滞回的贡献。 VSM将补充现有的磁力计，并将促进需要分析磁性岩石组构的结构地质学和构造学研究。 PI的研究重点是测试下大陆地壳和岩石圈地幔中的流动模型，VSM将使对经历部分熔融的断层岩（假玄武质岩）的磁性进行新的研究。 在SIU岩石磁性实验室增加一个VSM将使其成为伊利诺伊州-密苏里州-肯塔基州地区独特的分析设施，将促进女学生的培训，并促进国际研究合作。

0521558FerreThis Major Research Instrumentation (MRI) Program grant supports acquisition of a Princeton Measurements 3900-04 Vibrating Sample Magnetometer (VSM) for the Geology Department at Southern Illinois University. The PI, Eric Ferre, will use the VSM to develop methods for measurement of the high field anhysteresis of magnetic susceptibility (HFAMS) and to train students in magnetic measurements. The HFAMS method can resolve the respective contributions of paramagnetic and ferromagnetic sources to the anhysteresis of magnetic susceptibility. The VSM will complement an existing susceptometer and will facilitate research in structural geology and tectonics that requires analysis of magnetic rock fabrics. The PI's research focuses on testing flow models in the lower continental crust and in the lithospheric mantle and the VSM will enable new studies of the magnetic properties of fault rocks which have experienced partial melting (psuedotachylites). The addition of a VSM in the SIU Rock Magnetics Lab will make it a unique analytical facility in the Illinois-Missouri-Kentucky region, will facilitate training of female students, and foster international research collaborations.***
