Abstract

Abstract

Anisotropy of magnetic susceptibility (AMS) has been widely utilized to study orientation of magnetic minerals due to the paleo-flow, and direction of magnetic minerals or their recrystallization caused by tectonic stress. We presented the AMS principle and parameters, and studied AMS changes in:(1) two basalt samples (unheated and heated) that have experienced tectonic deformation, with multidomain (MD) titanomagnetite as dominant magnetic minerals, and this is from a previous study; (2) lake sediments that are majorly characterized by MD magnetite. The results show that AMS can sensitively investigate orientation of magnetic minerals.
