山东省肥城陆房地区萤石矿成矿地质条件及找矿方向

Geological Conditions of Ore-forming and Prospecting Direction of Fluorite Deposit in Lufang Area in Feicheng City of Shandong Province

肥城陆房地区是一个重要萤石矿分布区,目前评价的2个萤石矿,分别位于九山和赵家庄矿区,赋存于二长花岗岩中,受NE,NNE向构造控制,均为岩浆热液充填型。从这2个萤石矿的矿床地质特征入手,结合国内已有萤石矿资料,分析肥城陆房地区的成矿地质条件及矿床成因,总结其成矿规律,并指出今后该区找矿方向。

Lufang area in Feicheng city is an important fluorite distribution area. At present, 2 fluorite deposits have been evaluated. They are located in Jiushan and Zhaojiazhuang mine areas respectively, and occured in adamellite, controlled by structures with the trend of NE and NNE. They are both magmatic hydrothermal filling type. Starting from geological characteristics of the two fluorite deposits, combining with domestic existing fluorite deposit datas, metallogenic geological conditions and origins of Fanghu area in Feicheng city have been analyzed, its mineraliza-tion law has been summarized, and the direction of ore-prospecting in this area in the future has been pointed out.
