Atumi


Dolerite extends along the coast of northeastern Honshu, it is well exposed for c. 15km, it is up to 4 km wide in outcrop and comprises over 20 intrusive sheets, which vary from less than 1 km to over 5 km in length and less than 10m to over 300 m in thickness (Kushiro 1964).
Age probably late Miocene (Kushiro 1964).
