摘要
本文对小竺萤石矿区的地质特征、矿床特征、矿石特征及矿床成因进行了分析研究,研究显示:矿区内F1断裂为主要的控矿储矿构造,燕山期黑云母二长花岗岩为主要的成矿母岩;该萤石矿为热液充填型萤石矿床,矿石类型可分为萤石型、石英—萤石型、萤石—石英型三类。结合区域成矿地质背景及周边新发现萤石矿点特征分析认为,矿区外围区域沿F1断裂带存在着较好的成矿潜力与找矿前景。
In this paper, the geological characteristics, deposit characteristics, ore characteristics and deposit genesis of Xiaozhu fluorite mining area are analyzed and studied. The research shows that the F1 fault in the mining area is the main ore control and storage structure, and the Yanshanian biotite monzogranite is the main metallogenic parent rock, the fluorite deposit is a hydrothermal filling fluorite deposit. The ore types can be divided into fluorite type, quartz fluorite type and fluorite quartz type. Combined with the regional metallogenic geological background and the characteristics of newly discovered fluorite ore spots around the mining area,it is considered that there is good metallogenic potential and prospecting prospect along F1 fault zone in the peripheral area of the mining area.
