Abstract

The copper deposits in Goseong district, Gyeongnam area are fissure filled copper veins emplaced on Cretaceous Goseong formation and andesitic rocks. Occurrence of ore veins and mineral paragenesis suggest a division of the hydrothermal mineralization into three stages: stage 1, deposition of arsenopyrite, pyrite, quartz, chlorite and epidote; stageII, deposition of pyrite, chalcopyrite, galena, sphalerite, electrum, pyrargyrite, tetrahedrite, silver sulfosalt minerals, quartz, chlorite, sericite and miner amount of calcite; stage III, formation of barren calcite veins. Filling temperature of fluid inclusions in quartz of stage II, range from 260 to 360 C and salinities from 6.2 to 13.6 weight percent NaCi equivalent.
