A small displacement, about two meters or less, of a manganese ore deposit is called "Hitokase Danso", meaning "one-frame fault". The movement on the fault had evidently occurred before the manganese deposit was formed, and most of the shear zones have been mineralized by various manganese ores. The manganese ore deposit itself, therefore, has not been displaced by the fault movement, although slickensides on such later formed manganese minerals indicate the renewed movement of minor scale along the one-frame fault.
