摘要
安徽省金寨县沙坪沟钼矿属典型的花岗斑岩型钼矿床,花岗斑岩体具富酸、富碱、高钾的特点,钼矿化与钾化、硅化、绢云母化关系密切。对应钼矿化范围出现较强的Mo异常,ΔT表现为相对负磁异常。本文作者根据矿床的地、物、化特征构建了沙坪沟花岗斑岩型钼矿综合找矿模式,依照该模式客观评价了沙坪沟整装勘查区多个Mo异常,取得了较好的应用效果。
The Shapinggou molybdenum ore deposit in Jinzhai County,Anhui Province is a typical granite porphyry molybdenum deposit,and the granite porphyry is rich in acid,alkali and potassium,and molybdenum mineralization is closely related to potassium alteration,silicification and sericitization.Relatively intense molybdenum anomaly corresponds to the area of molybdenum mineralization,with ΔT showing relative negative magnetic anomaly.Based on the geological,physical and chemical characteristics of the deposit,the authors built up a comprehensive ore prospecting model for the Shapinggou granite-porphyry molybdenum ore deposit,and objectively evaluated several molybdenum anomalies in the Shapinggou package exploration area according to the model,which proved good for the obtained result.
