贵州东部镇远-凯里一带于新元古代下江群浅变质岩中分布有一套断裂构造控制的铅锌(铜)矿床,以金堡铅锌(铜)矿床最为典型,其构造位置位于江南造山带的西北缘,隶属鄂湘黔铅锌多金属成矿带。这一类型铅锌矿床与该区广泛分布的密西西比河谷型(MVT)型铅锌矿床在产出形态、赋矿围岩、矿石矿物和脉石矿物组合上均有很大的区别。目前,对此种类型的铅锌(铜)矿床的研究主要集中在矿床地质特征上(刘灵等,2008),仅有少量对成矿流体性质的讨论(杨宗文等,2015)。本文对以该
There is a Pb-Zn (Cu) deposit controlled by faults in the Neoproterozoic Xiajiang Group metamorphic rocks in the Zhenyuan-Carey area of eastern Guizhou. The Cu-Pb-Zn (Cu) deposit is most typical and is located in the Jiangnan orogenic belt Belt of the northwestern margin, under the Hubei, Hunan and Guizhou lead-zinc polymetallic belt. This type of Pb-Zn deposit is very different from the broadly distributed Mississippi Valley-type Pb-Zn deposit in this area in the aspects of output patterns, ore-hosting rocks, ore minerals and gangue minerals. At present, the research on this type of lead-zinc (copper) deposit mainly focuses on the geological characteristics of the deposit (Liu et al., 2008), with only a few discussions on the properties of ore-forming fluids (Yang Zongwen et al., 2015).
