The PIs will investigate an hypothesis that the anisotropic acquisition of certain remanent magnetizations will be insensitive to mineralogical variation, and will thus be solely controlled by the degree of particle alignment. Remanent anisotropies therefore ought to provide a much clearer indication of principal strain magnitudes. Partial anhysteretic remanent magnetization (pARM), which has been shown to be an effective means of recognizing grain-size variation in magnetite, can be potentially used to estimate the degree of particle alignment as a function of grain size.

PI将研究一种假设，即某些剩余磁化的各向异性获取将对矿物学变化不敏感，因此将仅受颗粒取向程度的控制。因此，残余各向异性应该能更清楚地指示主应变的大小。部分磁滞剩余磁化强度(PARM)已被证明是认识磁铁矿中颗粒大小变化的一种有效手段，可以用来估计颗粒取向程度与颗粒大小的关系。
