黔西南和黔东南是贵州的两个主要产金地区，大部分金矿都产于浊积岩中。但黔西南的金矿主要是含金蚀变岩型（或称卡林型、微细浸染型），以不可见金为主；黔东南的金矿却是含金石英脉型，以明金为主。这两种金矿都产在造山带，赋矿围岩是浊积岩，区内岩浆侵入作用不显著，成矿受背斜与断裂控制，成矿温度不高，矿石物质成分基本一致。研究表明，产生不同类型矿化的原因主要在于：黔东南地区的容矿岩石是浅变质的硅质碎屑岩，碳酸盐矿物很少；而黔西南地区是未变质的富钙硅质碎屑岩，碳酸盐矿物多。前者形成石英脉型金矿床，后者形成蚀变岩型金矿床。

Southwestern and southeastern Guizhou are two major gold metallogenic areas in China , and a mass of the gold deposits occur in turbidites .The gold deposits from the former area belong to altered rock type ( i.e.fine-disseminated type or Calin type ) , major in invisible gold .While the latter one belongs to quartz vein type, with visible gold.However, the deposits from both of metallogenic areas emerge in orogenic belts , where the turbidites are gold-bearing rocks , and the magmatism is slight in these areas .Anticlines and fractures control gold mineralization , ore-forming temperature is not high , and all these deposits are similar in ore mineral contents .The study demonstrates the reason of the different mineralizations in these two metallogenic areas as that the host rocks in southeastern Guizhou is metamorphosed siliciclastic rocks with rarely carbonate minerals ;while the host rocks in southwestern Guizhou calcium-rich unmetamorphosed siliciclastic rocks , with abundant carbonate minerals .Thus the quartz vein-type formed in the former while the altered rock type formed in the latter .
