영문 초록

Epithermal Mn-Au-Ag deposits of subvolcanic type in the Yeongil area discovered by one (Soo Jin Kim) of the present authors was studied with emphasis on their mineralogy, genesis and future potential. Mineralization is genetically related to volcanic activities of the Tertiary Period, which have produced porphyritic rhyolite, granite porphyry, felsitic rhyolite and agglomerate. Ore deposits are closely associated with felsitic rhyolite. They occur as breccia-filling, veins, or networks. Mineralization is characterized by rhodochrosite-sulfide ores of brecciatype in the central zone, and sulfide ores of disseminated type in the outer zone. Sulfides consist mainly of pyrite and marcasite, with minor chalcopyrite, sphalerite, argentian tetrahedrite, galena and gold in the central zone, and of pyrite, marcasite and argentian tetrahedrite in the outer zone. Sulfides are generally not easily identified with naked eye because of their very fine-grained nature. Wall rock alteration zones are also developed around ore deposits over the large area. Occurrence of ore deposits and the nature of mineralization indicate that the uppermost portion of ore deposits are now exposed on the surface, and therefore, the main mineralized zones are expected in depth.
