Abstract
Slickenside is the microstructure which is caused by faulting and has glossy. The slickenside is often found on the fault plane. The formation process of the slickenside is important to understand the faulting with the slickenside. This investigation reports the detail of the formation of the slickenside based on the characterization of the slickensides collected from the fields and the experiments for reproducing the slickensides, the characterization of the microstructure of the recovery samples.
