湘黔桂地区分布有大量浊积岩型金矿床，为确定本区浊积岩型金矿床的分布特征及成矿规律，系统分析了区域地质概况和区域金矿类型。研究结果表明，地层控矿具有全区域穿层成矿特征，局部岩性控矿的特点；由西南向北东方向，区域金成矿时代具有从加里东期向印支-燕山期趋新的时空分布特征；区域变形、变质程度作用对成矿作用强弱有较大影响。区域金矿田位于巨型推覆含金剪切断裂带中，大型金矿床一般都产在一级深大断裂旁侧的次级断裂中；多期成矿特征明显；并与岩浆岩的关系非常密切，金矿周围通常都有岩体的产出。

In order to make out the distribution characteristics and ore-forming regularities of turbidite-hosted gold deposits that widely exist in Hunan-Yunnan-Guangxi Region ,general geological survey of the region and gold deposit types in it are systematically analyzed .The results show that in the perspective of ore-controlling strata ,penetration ore forming occurs in regional scale and ores are controlled by lithology in the local;trending WS-NE,the mineralization goes younger from Caledonian to Indosinian-Yanshanian;gold fields in the region are located in huge push-over gold-bearing shear fault zones;the degree of deformation and metamorphism have fairly strong impacts on metallogenesis . Large-scale gold deposits usually occurs in secondary faults next to the primary deep fracture ,has an evident feature of multi-stage mineralization and a close relation to magmatic rocks , there are usually rock bodies neighboring the gold deposits .The degree of deformation and metamorphism might have fairly strong impacts on metallogenesis in the re-gion.
