| 摘 要： | 通过对个旧高松矿田的构造地质调查、区域成矿构造背景研究和以往勘探资料系统整理和分析，初步厘定了个旧高松矿田成矿构造系统，并将其解析为印支中晚期—燕山早期近EW向成矿构造子系统、燕山中晚期NE向成矿构造子系统、喜山早-中期岩溶成矿构造子系统。近EW向成矿构造子系统控制区内有利含矿岩系空间分布，含矿岩系的层序构造是层间氧化矿重要的控矿因素；NE向成矿构造子系统控制矿田内燕山晚期花岗岩的侵入就位及层间氧化矿和接触带矿的产出；喜山早-中期岩溶成矿构造子系统控制岩溶残坡积型和溶洞沉积型砂锡矿的形成。EW向与NE向构造交接复合，形成了向断凹式、羽列式、背突式、断裂-接触带构造式等复合控矿构造样式。此外，构造也控制了矿体的产状。根据这些控矿规律，可有效地进行找矿预测。

| Abstract: | Through geological tectonic survey, analysis of regional metallogenic tectonic background and collation of the previous prospecting data the metallogenic tectonic system of Gejiu Gaosong ore field is defined including three sub-systems, i.e. Middle-Late Indosinian-Early Yanshanian EW sub-system, Middle-Late Yanshanian NE sub-system and Early-Middle Himalayan karst sub-system. The EW sub-system controls distribution ore-bearing rock sequence and the sequential structure controls inter formational oxidized ore; the NW sub-system, intrusion and emplacement of Late Yanshanian granite and inter formational oxidized ore at contact zone; the karst sub-system talus and slope residual Sn placer and sedimentary Sn placer in cave. Intersection of EW and NE sub-system forms fault-concave, en echelon, back-projection structures and fault contact zone. Such structures control occurrence of ore body. According to the above mentioned ore-control factors can be effectively made ore prediction for future prospecting in the ore field. |
