摘要：黔西南是滇黔桂卡林型金矿矿集区的重要组成部分,据其古地理环境可划分为台地相和盆地相两类,且二者均有大型、超大型卡林型金矿分布,因此,对比黔西南地区卡林型金矿典型成矿特征,对该地区找矿勘查可起到一定的指导意义。研究选取太平洞金矿、百地金矿分别作为台盆相的代表矿床,从区域地质背景、矿床地质特征进行了对比研究,总结出了台盆相卡琳型金矿在区域地质、控矿构造、热液蚀变、矿物共生组合、异常元素特征等方面均具有典型特征,可在找矿勘查工作中依据沉积区域不同有针对性地开展工作。
Southwestern Guizhou is an important part of the Dian-Guan-Gui Carlin-type gold deposit concentration area,which can be divided into platform facies and basin facies according to its paleogeographic environment,and both of them have the distribution of large and super-large Carlin-type gold deposits,so the comparison of the typical metallogenic characteristics of Carlin type gold deposits in Southwestern Guizhou can play a certain guiding significance for the prospecting and exploration in this area.Taipingdong gold deposit and Baidi gold deposit are selected as the representative deposits of platform-basin facies in this study.The regional geological background and geological characteristics of the deposits are compared and studied.It is summarized that the Carlin-type gold deposits of platform-basin facies have typical characteristics in regional geology,ore-controlling structures,hydrothermal alteration,mineral paragenesis and abnormal element characteristics.In the prospecting and exploration work,the work can be carried out according to different sedimentary areas.
