| 摘 要： | 西藏驱龙斑岩铜矿床的发现是近年我国地勘行业找铜工作的重大突破之一。在发现找矿线索、确定成矿类型和评价找矿前景的过程中,勘查地球化学起了举足轻重的作用。1∶20万区域化探异常圈定了Cu-Mo矿化的范围,异常追踪查证工作确定了Cu-Mo矿化类型和找矿的有利地段。通过测区系统的地球化学勘查工作,结合地质构造资料,认为驱龙地区存在典型的斑岩铜矿床地球化学异常模式,矿化体剥蚀程度很浅,是找寻以斑岩型Cu-Mo矿化为主的超大型铜钼矿床的良好远景区。

| Abstract: | The Qulong Porphyry Copper Deposit is discovered in Tibet,it is one of the significant breakthrough in Chinese geology and exploration works for copper deposits in resent years. The exploration geochemistry play a decisive role in discovering the ore guide of prospecting,ascertaining the genetic types of mineral deposit and evaluating the foreground of prospecting. We circled Cu-Mo mineralization range using regional geochemical anomalies of 1:200000 scale,and ascertained its mineralization types and perspective targets by follow-up anomal survey.We consider that there is geochemical anomaly pattern of typical porphyry copper deposit in the Qulong area,through systematic exploration of geochemistry in the mineral district with the geological and structural data. The degradation level of orebody is very shallow. The Qulong area is a good prospect to looking for supper large-scale copper-molybdenum deposit with the porphyritic type Cu-Mo mineralization as its main ingredient. |
