摘要
利用地球化学块体新理论研究西秦岭大约8万km2的1∶20万图幅化探数据,圈定Ag地球化学块体。通过研究其地球化学块体内部结构套合的地球化学模式,逐步、追踪大型至特大型矿床可能存在的地点。圈定成矿远景区,确定银矿找矿靶区,利用成矿率类比,进行资源量预测。该研究成果,对西秦岭战略性矿产资源预测及勘查工作部署具有指导意义。
Using about 80,000 km^2 of 1：200 000 regional geochemical prospecting data, the authors delineated the Ag element geochemical block in west Qinling area, studied the internal geochemical model, traced the probable places of large - superlarge type deposits. With the analogue method of metallogenic rates, the resource quantity was also predicted. The results obtained will play a guiding role in strategic ore resource prognosis and exploration arrangement of this area.
