초록
The Yeonhwa Lead and Zinc Mine is located in northern part of Kyeongsang-Buk-Do, Korea, and is economically most important mine because it produces most part of the output of lead and zinc minerals in the country. Ore deposits of the mine are localized in the Pungchon Formation and several limestone seams of upper Myobong Formation in Cambrian Age. Ore solution ascended along the fractures of N-S, NE-SW or NW-SE trends and along slate and limestone boundary, and then replaced selectively limestone to make ore bodies. Skarn minerals are consisted of hedenbergite, diopside, and main sulfide mineral orebodies are composed of galena, zincblende, pyrrhotite, pyrite and a minor amounts of arsenopyrite and chalcopyrite.
