摘要
黄沙坪矿床位于南岭构造成矿带北缘中段,是一个铅锌金属和钨钼多金属均达到大型矿床规模的矿产地,目前已经被列为资源危机矿山。五矿勘查在黄沙坪边深部找矿勘探项目,在-400 m标高以下钻孔中见到厚度大、品位高的矽卡岩型铅锌矿体和矽卡岩型铜矿体,验证了五矿勘查研究的黄沙坪矿床成矿地质模型和找矿勘探模型。根据最近找矿成果,认为黄沙坪矿床矿体呈中心对称的环带结构,推断黄沙坪南部也有较大的找矿潜力。而且,成矿的隐伏岩体侵位空间具有向东南方向的雁行排列特点。
Huangshaping Pb-Zn deposit,located in the middle of the northern margin of Nanling metallogenic Region,is a large scale of lead and Zinc polymetallic mineral deposit,associated with tungsten and molybdenum.Presently,it has been listed as a resource crisis mine.Minmetals Exploration and Development Co.,Ltd(MED)carried out the desktop review of geological modeling and the exploration method,conducted the exploration program on deep ward of the Huangshaping ore body.The drill holes intersected large thickness and high grade of skarn type Pb-Zn and Cu ore bodies below-400 ASL.the exploration progress verifies the metallogenic geological model as well as prospecting and exploration method of Huangshaping deposit.According to the recent exploration progress the author believes that the ore bodies of Huangshaping deposit show a centrosymmetrical ring character on plan map,and infers that the southern area of Huangshaping Deposit is highly prospective for economic mineralization bodies.Moreover,the mineralised concealed masses were emplaced with a characteristic of southeast trending echelon array.The new clues discovered and new understanding obtained have certain significance for the prospecting work in the area of deep-ward Huangshaping Mine.
