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.

磁各向异性等磁性技术有望提供一种测量变形岩石中有限应变的有效方法。 然而，由于多种因素，这些方法目前并不稳健。 该项目将利用明尼苏达州北部的汤普森地层研究磁各向异性的矿物学控制。 预计结果将证明变形沉积岩的成分对各种磁性的影响，目标是开发一种可靠的应变测量工具。
