摘要
黔东南大地构造条件特殊,其北西侧为扬子准地台(Pt),南东侧为华南褶皱带(Pz1)。在该范围内大部分铅锌矿床分布在凯里—三都深大断裂带两侧,许多铅锌矿床具有"界面控矿"之特点。通过研究,这些控矿界面可划分为深大断裂界面、岩体侵入界面、硅—钙界面三种主要类型。各类控矿界面对铅锌矿床的区域成矿有着重要意义。
The tectonic condition of SE Guizhou is special, on the NW side is Yangzi paraplatform （Pt）, whereas on the SE side is South China fold belt （ PZ1 ）. In this area, most Pb-Zn deposits are on both sides of Kaili-Sandu macrofault. Many Pb-Zn deposits are characterized by the ＂boundary ore-control＂. According to the study, the ore-control boundary can be divided into 3 main types, ie the macrofault boundary, intrusion boundary of rock body and Si-Ca boundary, which are significant in the regional metallogenesis of Pb-Zn denosit.
