Also known as folded rock, it was collected near a fault that dates back 100 million years ago.
This rock has been deformed by the intense heat and pressure of the plates, resulting in a unique wave pattern.
One hundred million years ago was the heyday of dinosaurs, and this is a valuable stone that gives us insight into what the Japanese archipelago was like at that time.
The sheath-shaped folded rocks of Numashima, Hyogo Prefecture, where the faults are connected, are designated as an Important Cultural Property of Hyogo Prefecture.
It is a type of metamorphic crystalline schist that contains a complex mixture of iron, magnesium, aluminum, carbon, etc. in chlorite, forming black layers on which white silicon is layered.
It may also contain sparkling stilbromelenes, making it a very valuable stone.
