安徽怀宁县长岭铅锌矿体地质特征及矿床成因分析

Geological characteristics and genesis of Changling lead zinc deposit in Huaining County, Anhui Province

怀宁县长岭矿区位于扬子板块前陆带,出露古元古界至第四系地层。本文通过对长岭矿区发现的6处铅锌矿(化)体地质特征进行分析研究,然后从矿床的控矿因素、成因类型及找矿标志等方面对该类型矿床进行总结。认为矿床属于中低温热液充填型矿床,为周边同地质背景区域在寻找热液充填型矿床具有重要参考意义。

Changling mining area in Huaining County is located in the foreland belt of Yangtze plate,exposed from Paleoproterozoic to Quaternary strata.Based on the analysis of the geological characteristics of six lead-zinc ore bodies(mineralized bodies)found in Changling mining area,this paper summarizes this type of deposits from the aspects of ore controlling factors,genetic types and prospecting indicators.It is considered that the deposit belongs to medium low temperature hydrothermal filling type deposit,which has important reference significance for the surrounding areas with the same geological background in searching for hydrothermal filling type deposits.
