对羊拉铜成矿富集区新发现的斑岩体的地质地球化学特征及其相关的铜多金属矿化进行了研究,认为斑岩形成于同碰撞造山期,属成矿斑岩。与斑岩有关的矿化带从岩体向外可分为蚀变斑岩带、隐爆角砾岩带和脉状矿化带,且矿化逐渐增强。各带的矿物、蚀变及成矿元素组合特点反映成矿物质主要来源于斑岩,成矿类型为斑岩型,成矿时代属于燕山早期。
The geological and geochemical characteristics of the newly discovered porphyry bodies and their associated copper polymetallic mineralization in the copper-bearing ore-rich area of Yangla have been studied. It is believed that the porphyry was formed during the syn-collision orogeny and belongs to the ore-bearing porphyry. The porphyry related mineralization belts can be divided into altered porphyry belts, cryptoexplosive breccia belts and vein mineralized belts outward from the rock mass, and the mineralization gradually increases. The characteristics of mineralization, alteration and ore-forming elements in each belt reflect that the ore-forming material is mainly derived from porphyry, the metallogenetic type is porphyry type, and the metallogenetic age belongs to the early Yanshanian.
