摘　　要：通过研究石隆矽卡岩型白钨矿点的成矿地质条件、矿化特征及成矿控制因素,探讨班公湖—怒江成矿带西段钨矿成因类型和找矿标志。结果表明:石隆白钨矿点的矿化类型主要为矽卡岩型,其次为云英岩型。基于矿(化)体已有地表工程揭露和矿产剖面测量结果,认为该地区具有较好的钨矿找矿潜力。该矿点的发现,对进一步认识班公湖—怒江成矿带成矿地质特征和找矿方向具有重要意义。This study investigated the genetic types and prospecting criteria of tungsten ore deposits in the western section of the Bangong Lake-Nujiang metallogenic belt by analyzing metallogenic geological conditions,mineralization characteristics and metallogenic controlling factors of the Shilong skarn scheelite deposit.The results show that the Bailong scheelite occurrences are dominantly skarn-type mineralization,followed by greisen type.Based on the results of surface engineering and profile survey of ore bodies,this study suggests that the area is of better potential for tungsten prospecting.The discovery of this mine is of great significance to further understanding the metallogenic geological characteristics and prospecting direction in the Bangong Lake-Nujiang metallogenic belt.
