滇西南芦子园超大型铅锌多金属矿床成矿模式与综合找矿模型

    Metallogenic model and integrated prospecting pattern of the Luziyuan Pb-Zn polymetallic deposit, southwestern Yunnan Province

    • 摘要: 滇西南芦子园铅锌多金属矿床是近年来在三江成矿省保山—镇康铅-锌-铜-铁-锡-金成矿带发现并评价的第一个超大型矿床。在前人研究成果的基础上,结合本区多年的工作成果,总结了芦子园超大型铅锌多金属矿床的找矿标志,并初步建立了矿床的成矿模式和找矿模型。研究表明,芦子园铅锌多金属矿床是以寒武系上统为容矿地层并提供初始矿源,印支期中基性岩浆岩提供部分成矿物质,并受燕山期和喜马拉雅期隐伏酸性侵入体控制的叠加改造型矿床。区域物化探异常特征表明,该多金属矿床具有超大型矿床的典型矿化特征与找矿标志。

       

      Abstract: The Luziyuan lead-zinc polymetallic deposit, tectonically located in the Baoshan-Zhenkang Pb-Zn-Cu-Fe-Sb-Au metallogenic belt of Sanjiang metallogenic Province, is a superlarge ore deposit discovered in recent years. Based on years of research work in this study area combined with previous achievements obtained by other geologists, the authors have summed up the prospecting criteria for the Luziyuan lead-zinc polymetallic deposit, and established an ore-forming model and prospecting pattern. It has been shown by preliminary studies that the Luziyuan lead-znic polymetallic deposit is a superimposed transformation-type deposit.The Upper Cambrian strata seem to have been its host rocks which might have provided initial ore source, and the Indosinian basic magmatic rocks provided some ore-forming materials; in addition, the location of the ore deposit was controlled by the Yanshanian and Himalayan concealed intermediate acid intrusive rocks.
