广西河池市坡平锑锌多金属矿床位于南华活动带北侧,桂北台隆(江南古陆)西南缘。通过野外地质找矿工作,现已圈定7个矿(化)体。矿体呈脉状,走向近SN向,沿走向或倾向有分支复合,尖灭再现或尖灭侧现等现象:赋矿岩性主要为白云质泥岩、绢云母泥岩、泥灰岩。该矿在箭猪坡锑多金属矿床南东侧,结合区域矿床对比,认为矿床属中低温热液裂隙充填型矿床。文章在普查成果基础上,通过成矿地质背景、矿区地质概况和矿床地质特征的阐述,着重对矿床成因、控矿因素、矿化富集规律及找矿标志进行分析,认为该区具有较好的锑锌成矿地质条件和找矿前景,是寻找大中型锑锌矿的有利地区。
The Poping Sb-Zn polymetallic ore in Hechi City, Guangxi Province is located by the north side of the Nanhua activity zone, in the southwestern part of the Jiangnan Old Block. Now 7 ore bodies was found through the field geological work. The ore bodies are veins with SN strike. In their strike or trend, the veins appear embranehments and then incorporate again, and they also can disappear then emergence too. The ore-bearing rocks are mainly dolomitic mudstone, sericite mudstone and marlite. The ore is lain to the east of the Jianzhupo Sb polymetallic ore field. Contrast with the regional ores, this ore is thought to be a middle-low temperature hydrothermal filling type. The authors analyses the geological conditions and geological characters of the ore forming and the prospecting criterias, suggest that there is a potential of Mid-big Sb-Zn polymetallic ore in this area.
