Abstract
The Samkwang mine is Cretaceous gold-silver-bearing deposits located in the western part of the Ogcheon belt The ore deposits have been emplaced within granite gneiss of the Precambrian age. The Au-Ag deposits are hydrothermal-vein type, characterized by arsenic-, gold- and silver-bearing sulphides, in addition to the principal ore-forming sulphides arsenopyrite, galena, sphalerite, chalcopyrite, pyrite and pyrrhotite. Their proven reserves are 355,000 MT, and grades are 8.4 g Au/t and 13.6 g Ag/t. On the basis of their structural characters, the Au-Ag-bearing quartz veins are classified into three types of ore veins; (1) The Main vein shows
삼광광산은 옥천대의 서부에 위치하는 백악기의 금-은 광상으로서 선캠브리아기의 화강편마암내에 배태되어 있다. 광산의 금과 은의 품위는 각각 8.4 g/t, 13.6 g/t으로서 가채 매장장은 335.000 MT으로 추정된다. 이 광상은 Au-Ag광물 이외에 유비철석, 방연석, 섬아연석, 황동석, 황철석, 자류철석을 함유하는 열수성 석영맥상광상이다. 광상을 이루는 맥들의 구조를 근거로 할 때 광화작용의 구조규제는
