黔西北-滇东北地区已探明大中型铅锌矿床6个,小型矿床和矿点比比皆是.五十年代,认为这些矿床与区内零星分布的火成岩岩墙、岩脉或岩株有关,属岩浆期后中低温热液矿床;六十年代,提出同生沉积成因;七十年代后,又出现沉积改造、热卤水成矿和多源多次多种作用成矿等观点.本文结合同位素地质特征、岩相古地理分析,阐述成矿条件,提出成矿模式,祈能有助于找矿工作的深入.
Six large and medium-sized lead-zinc deposits have been identified in the northwestern Guizhou-northeastern Yunnan area, with small deposits and mineral deposits abounding. In the 1950s, these deposits were considered to be associated with sporadic igneous rock dikes, dikes or rock masses in the area, In the 1960s, the genesis of syngenetic deposition was proposed, and after the 1970s, the depositional alteration, hydrothermal brine mineralization and multi-source multiple mineralization were also seen.In this paper, isotopes Geological characteristics, lithofacies palaeogeographic analysis, described the metallogenic conditions, proposed metallogenic model, pray can help to find the depth of the work.
