摘要
闽清牛路坑铅锌矿床地处闽东中生代火山岩成矿带上[1],产于晚侏罗世中酸性-酸性火山岩中,成矿与断裂构造及火山活动密切相关。矿区内已发现4个矿体,呈不规则似层状、脉状、透镜状,受南北向和北北东向2组断裂控制。通过对矿床地质、控矿条件、矿体规模及形态的特征分析,初步研究认为,该矿床应属裂隙带充填交代中-低温热液型铅锌矿床。
The Nuilukeng lead-zinc deposit, located at the metallogenic belt of Mesozoic volcanic rocks in Eastern Fujian, was found in the Late Jurassic intermediate-acidic and acidic volcanics. The mineralization has a close relation with the faulted structures and volcanic activity. Four ore bodies has been discovered in the mining area. The orebody exists as irregular quasi-stratiform, vein and lentoid and is controlled by the north-south trend and northnorth-east trend faults. Based on the analysis results of the ore geology, ore-control conditions, orebody size and orebody configuration, it is considered that the ore deposit in the surveyed area belongs to the lead-zinc deposit of the filling-metasomatism intermediatelow-temperature hydrothermal type.
