多宝山矿区多次构造岩浆活动,均伴随着热流体活动。在多期多阶段热流体的影响下,形成了样式繁杂的蚀变岩石。这些蚀变岩石在空间上有规律的分布就构成了矿区的蚀变分带。近些年来,对斑岩铜矿脉体的研究得到了诸多学者的重视。一些学者按照与成矿相关的围岩蚀变以及室内光薄片鉴定将脉体分为A脉、B脉、D脉和E The Duobaoshan mining area has repeatedly constructed magmatic activities, which are accompanied by thermal fluid activities. Under the influence of multi-stage and multi-stage hot fluid, complicated rock alteration is formed. The regular distribution of these altered rocks constitutes the alteration zoning of the mining area. In recent years, many scholars have paid attention to the study of porphyry copper porphyry. Some scholars according to the mineralization-related wall rock alteration and the identification of indoor photosynthesis, the veins are divided into A vein, B vein, D vein and E
