| 摘 要： | 本文系《七五》国家重点攻关项目中三级专题湘南锡铅锌多金属隐伏矿预测研究的部分成果。在系统研究多金属成矿地质环境后,从解剖重点矿田、矿床入手,研究区内成矿规律,分析两类(同熔、重熔)岩浆的同熔、重熔、分异演化机制和沉积成岩机理与成矿的内在联系,探讨物质来源,成矿溶液性质和矿床成因,进而划分出同熔岩浆、重熔岩浆和层控等三大成矿系列,并依据成矿方式、围岩蚀变、矿物组合、矿体产状等细分出22个矿化类型(亚类),建立了成矿模式。依据成矿与地质环境的关系及矿床分带特征,总结了寻找隐伏矿床的找矿模式(标志)和找矿系统,并进行了成矿预测。

| Abstract: | This paper is part of the achievement of the research subject of "Predicting Concealed Sn-Pb-Zn Poly-metallic ore deposits in Southern Hunnan Province "which belongs to a key subject of seventh five -year-plan of China. Studied polymetallic mineralization setting systematically, and based on the analysis of major ore field and deposit , the mineralization regularity, and the relationship between mineralization and mechanism of deposition, diagenesis and syntexis, remelting and differentiation of two types of magma (syntetic magma and remelted magma)were revealed; and the source of ore - forming material, the characteristics of ore -forming liquid and genesis of mineral deposit were discussed. According to the genesis of ore deposit, alteration of country rock, and mineral assemblage, three metallogenic series (syntetic magma, remelted magma and strata - bound), and 22 types of mineralization were proposed. And mineralization model and prospecting model for concealed ore deposit were suggested on the basis of the study of ore deposit zoning and relationship between mineralization and geological setting. |
