甘肃北山斑岩型铜矿成矿带属于世界古亚洲古生代斑岩带成矿域。该带20世纪50年代发现了公婆泉、白山堂两个中型斑岩型铜矿。以后对该区的找铜工作一度只重视了富铜,对斑岩型铜矿重视不够。本文从铜矿资源形势和古亚洲斑岩型铜矿成矿域的资源潜力分析着眼,论述了甘肃北山有利于斑岩型铜矿形成的构造环境和矿化作用,提出了甘肃北山斑岩型铜矿的找矿靶区和找矿建议。
The Beishan porphyry copper ore belt belongs to the Paleozoic porphyry belt metallogenic domain in the ancient Asia. The band found in the 1950s, the princess spring, Baishan Tang two medium-sized porphyry copper. After looking for copper work in the area once only attached importance to the rich copper, not enough emphasis on porphyry-type copper. Based on the analysis of the situation of copper resources and the resource potential of the porphyry copper deposits in the ancient Asia, the paper discusses the tectonic environment and mineralization that is favorable to the formation of porphyry copper deposits in Beishan, Gansu Province, Copper prospecting prospecting area and prospecting suggestions.
