Neutral metasomatic rocks of Illite-Chlorite zone

Sericite deposit in the middle Miocene (14 Ma) sericitization zone formed in dacitic tuff breccia of the Shitara Volcanic Rocks by intrusion of dacite dikes of the middle Miocene (15 Ma) Shitara central dike swarm. The Shitara Volcanic Rocks and the Shitara centeral dike swarm are considered as members of the Miocene Shitara Caldera Complex. The heat source of the deposit formation is dacite dikes. Formation age of the deposit was determined by K-Ar radiometric dating of sericite.
