摘要
栾川县大红金铅多金属矿床处于卢氏—栾川陆缘褶断带、三川钼钨铅锌金铜银硫成矿区内。上元古界栾川群南泥湖组为区内主要赋矿层位,该矿床为明显受断裂控制、与燕山期岩浆活动有关的中低温热液充填型脉状矿床。对该矿区野外地质特征观察及地质勘查成果资料综合研究,汇总该矿床的地质特征、地球化学元素异常特征,并对矿床成因、找矿标志进行了探讨,认为该矿区金、铅等多金属成矿的成矿地质条件优越,地球化学异常特征显著,具有形成一定规模金、铅多金属矿床的找矿前景。
The Dahong gold-lead polymetallic deposit in Luanchuan County is located in the lushi-Luanchuan County continental margin fold-and-fault zone and the molybdenum-tungsten-lead-zinc-gold-copper-silver-sulfur metallogenic area in Sanchuan.The Nannihu formation of the Luanchuan group of Neoproterozoic is the main ore-hosting horizon in the area.The deposit is a meso-low temperature hydrothermal filling vein deposit,which is obviously controlled by faults and related to magmatism in the Yan Mountains period.Based on the observation of the geological characteristics in the field and the comprehensive study of the results of geological exploration,the author puts forward the geological characteristics and geochemistry characteristics of the deposit,and probes into the genesis and prospecting criteria of the deposit.It is considered that the regional geology and geological conditions of gold,lead and other polymetallic deposits in the mining area are superior,and the characteristics of geochemistry anomalies are obvious,which have the potential to form gold,lead and other polymetallic deposits of a certain scale.
