摘要：
安徽省池州地区矿床类型主要有矽卡岩型、斑岩型、热液型、风化淋滤型、沉积叠改型等。矽卡岩型是本区主要的矿床类型，根据其成矿特点可进一步分为：层控式、复合式、接触式。矿床（体）主要赋存在S-O间剥离面奥陶系汤头组、泥盆系顶部层位、泥盆～石炭系界面、石炭系黄龙-船山组、二叠-三叠系碳酸盐地层。燕山早期中酸性岩浆岩、层间滑脱构造、有利成矿的碳酸盐地层、不同方向不同性质的构造结合部位是本区重要的成矿条件。本文在总结前人成果资料的基础上，建立了本区区域成矿模式，将矿床成矿系列主要划分为三个：①与燕山早期钙碱性幔壳同熔型第一次侵入体有关的以W、Mo为主的成矿系列；②与燕山早期钙碱性幔壳同熔型闪长岩类岩体有关的Cu、Fe、S、Pb、Zn、W、Mo、（Au、Ag）成矿系列；③与燕山晚期陆壳改造型富硅富碱花岗岩有关的Ag、Cu、Fe、Pb、Zn多金属成矿系列。%Major mineral deposits in the Chizhou area of Anhui Province are of skarn,hydrothermal,weathering and leaching,depositional superimposition and reworking types. Dominating in the area,the skarn type is further divided in-to the strata-bound,mixed and contact subs according to its mineralization characteristics. Ore bodies are mostly hosted in the Tangtou Formation of Ordovician about the S-O stripping surface,the upper horizon of Devonian,the Devonian-Carbonaceous boundary,the Huanglong-Chuanshan Formation of Carbonaceous and carbonate strata of Permian and Tri-assic. Important mineralization conditions in the area include the early Yanshanian intermediate-acid magmatic rock,in-terlayer decollement,favorable carbonate stratum,the binding place of structures of different direction and different na-ture. On the basis of a summary of previous work results of other geologists,this paper established regional metallogen-ic models for this area classifying mineral deposits into three major series: (1) W,and Mo-dominant series related to early Yanshanian calc-alkaline mantle-crust syntectic first intrusive;(2) Cu,Fe,S,Pb,Zn,W,Mo,(Au,Ag)series having to do with early Yanshanian mantle-crust syntectic diorite intrusion;(3) Ag,Cu,Fe,Pb,Zn polymetallic series con-cerned with late Yanshanian continental crust reworking type Si-and alkali-rich granite.
