 羊拉铜矿主要由里农、路农、江边3个矿段组成。含矿岩系为下泥盆统江边组中段-中上泥盆统里农组上段,产有层状和似层状火山-喷流沉积矿体;印支-燕山早期具岛弧性质的中酸性岩浆侵入,形成矽卡岩型和改造叠加矿体;构造-岩浆演化至燕山早期末形成斑岩和断裂构造中脉状矿体,是一个具有巨大找矿潜力的既受层控,又绕岩体,从岩体穿插至围岩之中的沉积-斑岩-矽卡岩-脉状复合型铜矿床。通过找矿勘查实践,结合矿区地球物理和地球化学特征、遥感信息建立了勘查技术模型,进行缺位预测,在里农与路农矿段之间找到了层控矿体。 更多还原

【Abstract】 The Yangla copper deposit consists of Linong,Lunong and Jiangbian ore section.The ore-bearing rocks are composed of middle section of Jiangbian formation in lower Devonian-upper part of Linong formation in middle-upper Devonian,bearing stratiform and stratiform-like volcanic-sedimentary exhalative orebodies;Skarn type and superposed transformation orebodies were formed by the intrusion of the Indo-early Yanshanian intermediate-acid intrusive with the nature of the arc magmatic;Formed the porphyr... 更多还原
