| Abstract: | A mechanism of migration and secondary enrichment of gold in oxidized zone of gold deposits in a high and cold and arid zone is discussed Capillarity results in ascending migration of Au(S 2O 3) 3- 2 to near surface S 2O 2- 3 is oxidized,forming SO 2- 4,meanwhile,Au is disproportionated to Au |

| Keywords: | oxidized zone of gold deposit a high and cold and arid zone mechanism of secondary enrichment of gold capillarity |
