摘要
黄金山重晶石矿位于华北地台南缘,成矿地质条件优越.重晶石矿赋存于熊耳群马家河组安山岩,共圈出两个工业矿体.近矿围岩蚀变类型有硅化、绢云母化、绿泥石化、碳酸盐化等,其中硅化、碳酸盐化和绿泥石化与成矿关系密切;找矿标志有断裂构造标志及围岩蚀变标志;重晶石矿床受断裂构造、地层岩性和岩浆活动等因素联合控制,为热液充填型矿床.
Abstract
The Huangjinshan barite mine is located on the southern edge of the North China platform,with superior geological conditions for mineralization.The barite deposit occurs in the andesite of the Majiahe formation of the Xiong'er group,and two industrial ore bodies are circled.The types of wall rock alteration near the mine include silicification,sericitization,chloritization,carbonation,etc.Among them,silicification,carbonation,and chloritization are closely related to mineralization.The prospecting indicators include fault structure indicators and rock alteration indicators.The Huangjinshan barite deposit is controlled by factors such as fault structure,stratigraphic lithology,and magmatic activity,and is a hydrothermal filling type deposit.
