摘要
鄂东北梨木岭矿床北北东向断裂带内发现(铜)钼矿(化)体与钨矿(化)体,结合矿区近几年的普查成果,在综合研究该矿床地质、地球化学、地球物理特征基础上,构建矿区内受北北东向断裂控制的钼矿床综合信息的找矿模型。认为受北北东向断裂控制的钼矿床地球化学具有W-Mo-Cu-Ag-Bi-Sn-Pb-Zn元素组合异常特征,地球物理具有高极化率、高电阻率的电性特征;土壤测量W-Mo-Cu-Ag-Bi综合异常和激电中梯高极化率异常与赋矿蚀变断裂带范围吻合,可作为勘查工作的重点地段;激电测深高极化率异常与钼矿(化)体吻合较好,可间接定位深部矿(化)体赋存位置。该矿床综合信息找矿模型的构建对于矿区下步的找矿工作以及东大别南麓同类型矿床的发现具有指导意义。
The Limuling molybdenum-polymetallic deposit had found(copper)molybdenum mineralization bodies and tungsten mineralization bodies in the NNE faults in recent years.This paper constructs the synthetic prospecting model of molybdenum-polymetallic mineralization in the NNE faults,based on the deposit geology,geochemical characteristics and geophysical characteristics combining the recent reconnaissance survey results,which play an important role in the next reconnaissance works and the discovery in the east Dabie belt.The paper holds that molybdenum-polymetallic mineralization in the NNE faults owns the W-Mo-Cu-Ag-Bi-Pb-Zn geochemical assemblage anomaly and the high polarization,high electrucal resistivity geophysical anomaly.The W-Mo-Cu-Ag-Bi soil anomaly and the high polarization anomaly of the induced polarization intermediate gradient are consistent with the ore-host faults,which can be regarded as the key locality of the exploration work.The high polarization anomaly of the electrical sounding of induced polarization is consistent with the molybdenum mineralization bodies,which can indirectly be used locating the positions of deep ore bodies.
