The red-clay-type gold deposit in China

The red-clay type gold deposit discovered in southern China is a new type of gold deposit formed by supergenic processes . Although similarities to lateritic gold deposid in out-looking, the red-clay type gold deposid has obviously different features to lateritic gold deposid. Three examples of red-clay type gold deposit were investigated in this work ,which are Shangmanggang gold deposid in western Yunnan province, Laowanchang gold deposid in southwestern Guizhou province, and Shewushan gold deposid in southern Hubei province, China. Comprehensive studies have been carried out on the features of red-clay profile, on the features geological background to lateritization and miralization , on features of ore body and ore. The ore forming geological condition and the main characteritic of red-clay type gold deposit in China were summarized.
