Magnetic techniques such as magnetic anisotropy offer the promise of providing an efficient means of measuring finite strain in deformed rocks. However due to several factors the methods are not presently robust. This project will investigate the mineralogical control of magnetic anisotropy by use of the Thompson formation of northern Minnesota. Results are expected to demonstrate the compositional effects of deformed sedimentary rocks on various magnetic properties, with the goal of developing a reliable tool for measuring strain.

诸如磁各向异性之类的磁技术提供了提供有效方法在变形岩石中的有限菌株的希望。 但是，由于几个因素，该方法目前并不强大。 该项目将通过使用明尼苏达州北部的汤普森形成来研究磁各向异性的矿物质控制。 预计结果将证明变形沉积岩对各种磁性特性的组成效应，其目的是开发可靠的工具来测量应变。
