广西望天洞银金矿床地质特征及找矿标志探讨

Geological characteristics and prospecting indicators of Wangtiandong silver-gold deposit in Guangxi

文章在对北流市望天洞银金矿床矿区地质特征认识的基础上,研究了矿体特征、矿石特征及围岩蚀变,分析了矿床的控矿因素,提出以断裂构造、变质程度较低的岩性带、金属硫化物矿化强地段、围岩蚀变、强烈褐铁矿化露头作为该矿床的找矿标志的新思路。

Based on the knowledge of the geological characteristics of Wangtiandong silver - gold deposit in Beiliu city, in this paper, the author studied orebody characteristics, mineral characteristics and wall rock alteration, analyzed the ore controlling factors and proposed a new idea that fracture structure, lithizone with low metamorphic grade, blocks with strong metallic sulfide mineraliza- tion, wall rock alteration and outcrops with strong ferritization could be as prospecting indicators for this kind of ore deposit.
