摘要
勒玛擦地区位于班公湖—怒江成矿带西北部,毗邻多龙矿集区。通过分析勒玛擦地区成矿地质条件和典型矿点地质特征,提出该区找矿方向。结果表明,勒玛擦地区主要发育矽卡岩型铜铁多金属矿和斑岩型铜矿;矽卡岩型矿床受控于龙格组碳酸盐岩和早白垩世花岗闪长岩,斑岩型矿床与早白垩世花岗斑岩、花岗闪长斑岩等浅成侵入体有关。综合成矿地质条件和矿化类型,在勒玛擦地区圈定团结达坂铜铅锌铁找矿远景区和勒玛擦铜找矿远景区。
Lemama area is located in the northwest of Banggongco-Nujiang metallogenic belt and adjacent to Duolong mineralization district.By analyzing the metallogenic geological conditions and the geological characteristics of typical ore spots in Lemama area,the prospecting direction is proposed.The results show that skarn Cu-Fe polymetallic deposits and porphyry copper deposits are mainly developed in Lemama area.The skarn type deposit is controlled by the carbonate rocks of Longge Formation and the Early Cretaceous granodiorite.The porphyry type deposit is related to the shallow intrusive bodies such as the Early Cretaceous granite porphyry and the granodiorite porphyry.Based on the metallogenic geological conditions and mineralization types,Tuandaban Cu-Pb-Zn-Fe prospecting area and Lemama copper prospecting area are delineated in this area.
