摘要 对巴隆岩金矿成矿地质背景、矿体特征、矿石特征及其控矿因素等进行分析研究。认为区内矿体与NWW向断裂关系密切,NWW向昆中主断裂为矿床的导矿构造,NWW向F1断裂为矿床的配矿构造,矿区内F2,F3,F4,F5等NWW向次级断裂为矿床的容矿构造;尤其是在拐弯或膨胀处;强烈的印支期岩浆活动,剧烈的构造运动为金元素的活化、迁移、富集、沉淀提供了通道和成矿空间;矿石类型主要为构造蚀变岩型;重砂矿物标志、地貌标志、颜色标志、气味标志、化探异常标志等是该区的主要找矿标志。结合区域上成矿背景分析认为该矿区有着良好的找矿前景,并建议对矿床深部及外围做进一步工作。 In this paper, metallogenic geological background, ore body characteristics, ore characteristics and ore--controlling factors of Balong rock gold deposit have been analyzed and studied. It is regarded that gold ore bodies have close relation with faults with the trend of NWW. Main faults in middle Kunlun fault with the trend of NWW are guiding structures. F1 fault with the trend of NWW is the ore matching struc- ture. Secondary structures of F2, F3, F4, F5 with the trend of NWW are ore hosting structures. Strong In- dosinian magmatic activity and strong tectonic movements provide channels and mineralization space for gold activation, migration, enrichment and precipitation. Heavy placer material marks, geomorphic marks, color marks, smell marks and geochemical anomalies marks are main prospecting marks in this area. Combining with regional metallogenic background analysis, it is regarded that there is good ore prospect in this area. It is suggested that further work should be clone in the deep and periphery areas in this deposit.
