摘要
广西隆林卡林型金矿主要产于上二叠统合山组泥质条带状灰岩及砂质白云岩中,受背斜或穹窿构造核部的高角度正断层控制明显,矿体呈脉状或似层状,矿石类型包括块状、条带状、碎粒状等。根据金矿产状和下伏碳酸盐岩地层具有较高的金丰度,推测该地区金矿成因与热液流体活动密切相关;最后还对研究区找矿标志和找矿潜力进行了探讨。这项研究为我国西南碳酸盐岩地区寻找金矿提供了新的思路。
This paper summarizes the metallogenetic characteristics and genesis of Carlin-type gold deposits based on synthetical study of geological background of ore-formation, metallogenetic strata, ore-controlling structures and wall-rocks of the first discovered 3 Carlin-type gold deposits in Longlin region, NW Guangxi. It includes that this Carlin-type gold deposit is mainly located in the core of dome structures, and is controlled by the impure carbonate rocks and high angle normal faults. The further discussion of the origin of the Carlin-type gold deposits in NW Guangxi unveils some index or thoughts symbols for Carlin-type gold deposit exploration in SW China.
