Abstract
EBSD measurements using talc schists collected from the boundary between pelitic schist and antigorite serpentinite show talc CPO show the strong concentration of the normal direction of the (001) plane that is normal to the foliation. The strongest concentrations of the [100] and [010] directions of talc show the direction parallel to the lineation, and the direction parallel to the foliation and normal to the lineation, respectively.
