Lithology and Thickness
The metal deposits formed by this volcanism and associated hydrothermal activity are called ‘Kuroko', yielding copper, lead and zinc. Subsequent sedimentation is represented by thick marine siliciclastics; The upper part of 'Kuroko' is dominated by mudstone. Subsequent sedimentation is represented by thick marine siliciclastics. This succession has been regarded as a 'standard succession', based on which a local chronostratigraphy was established (Hujioka 1959).
