摘要
蓟县北部山区具有良好的夕卡岩型铜矿成矿条件,与河北省兴隆县寿王坟夕卡岩型铜矿具有相似的成矿模式。选取寿王坟铜矿作为蓟县夕卡岩型铜矿研究的典型矿床,参照矿产资源地球化学定量预测方法技术,计算出盘山预测区的剥蚀系数约为0.7,石臼预测区的剥蚀系数约为0.5,属于中-深度剥蚀;盘山预测区和石臼预测区的相似系数均为0.74,采用考虑剥蚀系数的面金属量法计算了蓟县夕卡岩型铜矿的预测资源量。
In the north mountains of Jixian area exist similar metallogenic conditions of Shouwangfen skarn copper deposit in Xinglong county, Hebei province. Following the metallogenic model of Shouwangfen copper deposit mineral resources of skarn copper ore in Jixian area is calculated with the geochemically quantitative prediction method. Denudation coefficient is 0.7 in Panshan prediction area, 0.5 in Shijiu area showing medium-deep denudation of the predition areas. The similarity coefficient of the two areas is 0.74,and resource of skarn copper deposits in Jixian by the areal productivity method of concerned with denudation coefficient.
