摘要
翠宏山矽卡岩型矿床产于加里东期蚀变碎裂白岗质花岗岩与早寒武纪海相碳酸盐接触带及其附近。按照不同的矿物组合划分出高温的铁钼钨(FMW)带、中温的铁钼锌(FMZ)带和中低温的铅锌(PZ)带。利用温度分带规律来指导矿体的圈定可使矿体形态接近真实,提高资源量计算的准确性,有利于指导矿山开采。同时也可以推广用于地表化学找矿。
The skarn-type deposits of CuiHong Mountain occurs near the contact zones between the Caledonian corrosive and cracked granite and the early Cambria marine carbonate rocks.According to the different mineral combination,the deposits were divided into three zones： hyperthermal Fe-Mo-W zone,mesothermal Fe-Mo-Zn zone and medium-microthermal Pb-Zn zone.The temperature zoning law could be used to locate the mine bodies and make the delineation of ore bodies close to the real ore bodies,thereby improve the accuracy of the resource calculation,and help guide the mining.At the same time the law can be used for the chemical prospecting on earth surface.
