Acquisition of a Vibrating Sample Magnetometer for the Paleomagnetism Laboratory, Western Washington University

0421457豪森这项重大研究仪器补助金为西华盛顿大学古地磁实验室购买普林斯顿测量3900-04振动样品磁强计(VSM)提供资金，该仪器带有高温炉。新的VSM将提供收集重要新数据的机会，这些数据将极大地增强WWU现有的古地磁和岩石磁研究计划，并将使新的研究路线和合作工作得以进行。现有的研究工作侧重于板块和地体(微板块或变形板块边缘区域)运动学和古地理重建，将磁性组构用作变形岩石的构造工具，以及磁性地层学研究，这些都将因为能够更全面地表征岩石和沉积物的磁性矿物学而得到极大的加强。其他新的研究方向将包括扩大高场磁化率各向异性作为变形深成岩、断裂带和吸积棱柱的岩组工具的使用，以及作为沉积岩中剩磁压实变浅的测量。其他新的研究努力还将包括利用岩石磁性来探索以喀斯喀特山脉高山湖泊为核心的全新世沉积物中记录的气候变化，以及旨在快速和廉价地检测区域湖泊中的城市污染的环境磁性。WWU物理系还将利用VSM进行先进半导体磁性研究的重要部分。WWU地质系和物理系的大量本科生和硕士研究生，以及来自该地区的游客，将从这一新设备中受益。

0421457HousenThis Major Research Instrumentation Grant provides funds for acquisition of a Princeton Measurements 3900-04 Vibrating Sample Magnetometer (VSM), with high temperature furnace, for the Western Washington University Paleomagnetism Lab. The new VSM will provide opportunities to collect important new data that will greatly augment the existing paleomagnetic and rock magnetic research programs at WWU and will also enable new research lines and collaborative work to be made. Existing research efforts focused on plate and terrane (micro-plate, or deformed plate margin regions) kinematics and paleogeographic reconstructions, use of magnetic fabrics as a structural tool in deformed rocks, and magnetostratigraphic studies will all be greatly enhanced by the ability to more completely characterize the magnetic mineralogy of rocks and sediments. Additional new lines of research will involve expanded use of anisotropy of high-field susceptibility as a petrofabric tool in deformed plutonic rocks, fault zones and accretionary prisms, and as a measure of compaction-shallowing of remanence in sedimentary rocks. Other new research efforts will also include use of rock-magnetic properties to explore climatic changes recorded in Holocene sediments cored from alpine lakes in the Cascade Range, and environmental magnetism aimed at rapid and inexpensive detection of urban pollution in regional lakes. The WWU Physics Department will also utilize the VSM for a significant part of their research on the magnetic properties of advanced semiconductors. A significant number of undergraduate and MS students in the WWU Geology and Physics Departments, as well as visitors from within the region, will benefit from this new device.***
