Kuroko-type Deposits of the Misaka-Koma Mountains in the Izu collision zone, central Japan: Their Occurrence and Geological Implications

We identified six Kuroko-type deposits in the Izu collision zone, central Japan, which formed as seafloor massive sulfides (SMS) Paleo-Izu Arc before its with Honsh? during middle Miocene. These are found same stratigraphic horizon (~15 Ma) Nishiyatsushiro and Koma groups, between basaltic volcanic sequence of Furusekigawa Formation (or equivalent) hanging-wall mudstone Tokiwa Group equivalent sedimentary unit Group).
