摘    要:本文通过对贵州罐子窑-茅口地区地面高精度磁测资料数据处理、化极和延拓,对圈定的弱磁异常进行地质解释,推断一些弱磁异常可能与浅成辉绿岩或热液活动有关。结合地物化遥成果,圈定了花贡铅锌金找矿远景区、罐子窑铅锌找矿远景区和花嘎铅锌铜金找矿远景区。而异常查证结果表明,所发现的铅锌矿化蚀变带均出现在推断的隐伏构造或隐伏侵入体附近,表明物、化探异常的出现应与深部岩浆和构造活动为成矿提供了热源和成矿空间有关,为寻找铅锌矿提供了间接找矿依据。

关 键 词:铅锌矿  地面磁测特征  罐子窑-茅口地区  贵州

Abstract:In this paper,by data processing,catalytic polarography and continulation to ground high precision magnetic survey information in northwestern Qinglong,it explains the zonal magnetic abnormality in the target area,concludes that some weak magnetic abnormality has relation with hypabyssal diabase or the hydrothermal activity.With the geophysical and geochemical prospecting results in the target area,it delineated Huagong lean-zinc and gold prospecting area,Guanziyao lead-zinc prospecting area and Huaga lead-zinc and copper prospecting area.According to the abnormality test,all the founded lead-zinc mineralization alteration zone appears near the structure or intrusive body,means that the geophysical and geochemical abnormality has relation with magmatic activity and tectonic activity,affords prospecting accordance for the lead-zinc deposit exploration.So it's thought that the prospecting area delineation by geology,geophysical and geochemical prospecting measures is reasonable.
Keywords:ead-zinc deposit  ground magnetic survey character  prospecting area  northwestern Qinglong  Guizhou
