云南德钦羊拉铜矿区矿床控矿因素及找矿远景

Analysis of the Ore-Controlling Factors of Deqen Yangla Copper Ore District in Yunnan and Its Ore-Hunting Prospect

羊拉铜矿为矽卡岩-斑岩型复合成因,同时存在早期(火山)沉积建造中的成矿元素预富集,多期成矿特征明显,是一个以斑岩成矿作用为主体的复杂成矿系统。矿区具有良好的找矿远景,无论是在矿区本部还是外围,开展资源评价、增加资源储量的潜力空间非常大。下一步找矿重点应主要放在里农矿段与路农矿段接合部、江边矿段北延、以及外围的贝吾、尼吕、通吉格、加仁等矿段及格亚顶、曲隆等地区。

Yangla copper deposit is of skarn-porphyry type and is characterized by ore-forming element pre-concentration in early （volcano） sedimentation setting and obvious multi-stage mineralization, involving a complex ore-forming process mainly with porphyry mineralization. The ore district has a good ore-hunting prospect and has great potentiality in the resource increase both within and around the district. The emphasis in the next stage ore-prospecting should be laid on the joint section between Linong and Lunong ore segments, the north extension of Jiangbian ore segment and the Beiwu, Nilu, Tongjige and Jiaren ore segments in the vicinity of the district and Geyading and Qulong zones.
