Abstract
The Weolseong diatreme was temporally and spatially related to the intrusion of the Gadaeri granite, and was -mineralized by meteoric aqueous fluids. In the Nokdong As-Zn deposit, pyrite, aresenopyrite and sphalerite are the most abundant sulfide minerals. They are associated with minor amount of magnetite, pyrrhotite, chalcopyrite and cassiterite, and trace amounts of Pb-Sb-Bi-Ag sulphosalts. The AsZn ore probably occurred at about
시간적-공간적으로 가대리 화강암과 관련되어 형성된 월성 다이아튜림은 천수에서 유래된 용액에 의해 광화되어 있다. 이 광상에서 광석광물은 황철석, 유비철석, 섬아연석이 대부분이고 극소량의 자철석, 자류철석, 황동석, 석석과 Pb-Sb-Bi-Ag 계의 광문이 있다. 유체포유물, 유비철석에서의 비소함량과 섬아연석의 철 함량에 의해 계산된 비소-아연 광화 온도는 약
