安徽省沙坪沟钼矿床蚀变及其分带特征
|
摘要
沙坪沟钼矿床蚀变类型有硅化、钠化、钾化、云英岩化、绢英岩化、黄铁绢英岩化、硬石膏化、萤石化等,与成矿有关的主要蚀变为硅化、钠化、云英岩化,黄铁绢英岩化发生在钼成矿之后;由下到上,由高温到低温将蚀变划分为三个带,即钾化、钠化、云英岩化综合带、绢英岩化带、黄铁绢英岩化带;工业矿体主要分布在钾化、钠化、云英岩化综合带中,绢英岩化带主要构成矿体顶板及分布部分低品位矿体,黄铁绢英岩化带主要分布于基本无矿体的地表及地下浅部。
The Shapinggou molybdenum ore deposit is involved in alterations such as silication,sodiumization,potassiumization,greisenization,sericitolitization,beresitization,anhydritization and fluoritization,of which beresitization post-dated molybdenum mineralization.From bottom to top,alteration is divided by temperature from high to low into a composite zone of potassiumization,sodiumization and greisenization,sericitolitization zone and beresitization zone.Industrial ore bodies occur in the composite zone,with the sericitolitization zone forming the ceiling and hosting low- grade mineralization,and the barren beresitization zone in the surface and shallow underground.
