宜里钼矿蚀变特征及其找矿意义

在野外调查、岩芯编录和岩矿鉴定的基础上,将宜里钼矿区的蚀变类型划分为硅化、钾化、绢云母化等主要类型,其中硅化和石英绢云母化与成矿关系密切。编制了矿区平面和剖面蚀变分带图,主要包括石英－白（绢）云母－黄铁矿化带（绢英岩化带）和绿泥石－绿帘石－方解石化带（青磐岩化带）2个蚀变带,与国内外典型的斑岩型钼矿蚀变分带相比,认为宜里钼矿以叠加蚀变为主要特征,即早期的硅化被后期的石英绢云母化和最晚期的碳酸盐化叠加。根据蚀变分带特征,推断严格控制矿体分布的F4断层总体上可能为一逆断层（成矿后活动）,暗示F4断层下盘可能还存在一定规模的钼矿体。同时,根据蚀变与矿化的关系,认为在主矿区的南段深部为最有前景的钼找矿勘查区。
