摘要:
研究目的 乐开铅锌矿床是近些年黔西北铅锌矿集区内新发现的矿床之一，与该矿集区内铅锌矿床主要受NW向断裂控制有所不同，乐开铅锌矿床严格受NE向断褶构造控制，与滇东北矿集区铅锌矿床具有一致的成矿地质条件。该研究对黔西北乐开地区乃至川滇黔接壤区铅锌矿深部找矿具有重要的指示意义。
研究方法 主要包括构造精细解析和构造地球化学等方法。
研究结果 该区控矿构造型式为典型的“多字型”和“入字型”，并划分出3种构造组合，分别代表 4种不同的构造体系：海西期—印支中期(早SN构造带)、印支晚期—燕山早期(NE构造带)、燕山中晚期(NW构造带)及喜马拉雅期(晚SN构造带)。断裂构造岩主要表现为低温成矿阶段的前缘晕元素组合(Sb-As-Hg)、中温成矿阶段的近矿晕元素组合(Zn-Pb-Cd)与中高温成矿阶段的尾晕元素组合(In-Sn-Ni-Cu)。
结论 NE构造带为该矿床的成矿构造体系，推断成矿流体在平面上自SW向NE向运移，提出矿区深部6个定位找矿靶区。
Abstract:This paper is the result of mineral exploration engineering.
Objective The Lekai lead-zinc deposit, located in the Pb-Zn deposit concentration of northwestern Guizhou, is one of the small-scale lead-zinc deposits newly discovered in recent years. Different from most lead-zinc deposits in the Pb-Zn deposit concentration of northwestern Guizhou, the Lekai lead-zinc deposit is controlled strictly by NE trending fault-fold structure, which is similar to most lead-zinc deposits in the Pb-Zn deposit concentration of northeastern Yunnan. The current research provided significant implications for the deep exploration in the Lekai lead-zinc deposit and the Sichuan–Yunnan–Guizhou Triangle area (SYGT).
Methods This study applied a large deal of detailed structural analysis on mechanical properties for faults and folds in the mining area and tectono-geochemistry method.
Results The results showed that duo-type and λ-type are the main ore-controlling structural styles in this area. Moreover, three tectonic associations have been divided, which are correspond to four tectonic systems, namely Hercynian to Mid Indosinian, Late Indosinian to Early Yanshanian, Mid-Late Yanshanian, and Himalayan epochs. The trace elements concentrations of tectonites represented three element associations of principal factors, including frontal halo elements (Sb-As-Hg) in low temperature ore-forming stage, mineralization-halo elements (Zn-Pb-Cd) in medium-low temperature ore-forming stage, and tail-halo elements (In-Sn-Ni-Cu) in medium temperature ore-forming stage.
Conclusions In four tectonic systems, ore-forming tectonic system corresponded with Late Indosinian to Early Yanshanian. According to anomaly features and their distribution regularities, the possible migration direction of ore-forming fluid is from southwest to northeast, and six target prospecting areas have been put forward in the depth of mining.
