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��
