Haenam pyrophyllite deposit occurred in the rhyolitic tuff of late Cretaceous age is located in the northern part of Haenam-gun, Jeonranam-do. The ore of the Haenam deposit is predominantly composed of pyrophyllite and illite accompanying such clay minerals as kaolinite, chlorite, and smectite. Pyrophyllite ore at the center of altered mass is often associated with kaolin minerals and high temperature minerals such as corundum, andalusite, and diaspore. On the basis of mineral assemblage the Haenam deposit can be devided into three alteration zones from the center to the margin of the deposit; the pyrophyllite zone, kaolinite zone, and illite zone. All alteration zones are associated with appreciable amounts of chalcedonic quartz. Those mineral assemblages indicate that hydrothermal solution which produced the Haenam deposit is strongly acidic solution with high silica and hydrogen activity and low
