Abstract

It was carried out to the survey on the lead-zinc and tungsten occurrences in the Kau Loc mineralized belt within northern Vietnam. The lead-zinc occurrence bear the ore body parallel to the bedding of limestone formation. Assuming the surface grade and geological reserve, Pb+Zn deposit is estimated to the small to medium-sized ore deposit. On the other hand, considering the distribution of small-scale stock intruding the Devonian limestone, it is thought that the tungsten occurrence has the proper geological conditions anticipating the presence of skarn mineralization. However, there is no evidence to recognize economic feasibility in the present situation because of the absence of detailed geology and ore deposit survey on the tungsten occurrence.

베트남 북부 카우록 광화대의 연-아연, 텅스텐 산출지에 대한 지질광상조사를 실시했다. 연-아연 산출지는 석회암층의 층리에 평행하게 광체를 배태하고 었다. 지표품위와 지질학적 매장량을 고려할 때, 연-아연 산출지는 소-중규모로 판단된다. 반면 데본기 석회암을 관입하고 있는 소규모 암주의 분포를 고려할 때, 텅스텐 산출지는 스카른 광화작용의 부존이 기대되는 적절한 조건을 가지고 있다. 그러나, 정밀지질광상조사가 결여되었기 때문에 현재 상황에서 경제적 타당성을 인지할 만한 증거는 없는 것으로 사료된다.
