A DISCUSSION ON THE GENESIS OF CARLIN TYPE GOLD DEPOSITS IN SOUTHWEST GUIZHOU,TAKING GEOLOGICAL AND GEOCHEMICAL CHARACTERISTICS OF NAGE GOLD DEPOSIT AS AN EXAMPLE
Abstract：The special geological and geochemical characteristics of Nage gold deposit has been introduced.The study show there are a lot of quartz veins occurred in the deposit,which related with gold mineralization,the content of CO2 in quartz is very high,the temperature is same as the gold deposits in region,the composition of H,O isotopes are arround magmatic water.The authors think the gold,solution and heat may come from deep magma reservoir. Some data of gold content in the rocks and S,C,H,O stable isotopes in the gold deposits,southwest Guizhou support the genesis above.The authors think Carlin type gold deposits in southwest Guizhou are low-middle hydrothermal deposits,they have same genesis,that is the gold,solution and heat from magma reservoir(mixed with some solution in upper rocks)…deep and big fault structure as passageway for ore fluid…ore-control by anti clines and faults in surface strata…ore-forming by metasomatism and filling.
