| 摘 要： | In this paper an intergrated geological and geochemical comparison is made of Carlintype and Carlin-like-type gold depostis in the region of South Qinling with their associated hydrothermal sedimentary lead-zinc pdposits,the Carlin-type deposits in the Yunnan-Guizhou-Guangxi gold triangle,China,the Carlin gold deposits,Carlin,western United States,and the Muruntau-type gold deposits in Uzbekistan.The comparative study indicates that the formation of these deposits has an intimate coupling relation with the mechanism of the tectonic movement of modern plates.Therefore,these deposits belong to those that were formed in the orogenic stage. They have the following similar characteristics:they are all sediment-hosted.occur in a tectonic environment of extensional rifting nature and show the characteristics of syngenetically modified mineralization.On the other hand,they alsso have noticeable differences:they are different in respect to their tectonic settings.association and structure of orogenic belts and complexity and strength of the modified mineralization.The regional tectonic evolution and extensive mineralization in orogenic belts are different expressions of the same continental dynamic process.

| Abstract: | In this paper an integrated geological and geochemical comparison is made of Carlintype and Carlin-like-type gold deposits
in the region of South Qinling with their associated hydrothermal sedimentary lead-zinc deposits, the Carlin-type deposits
in the Yunnan-Guizhou-Guangxi gold triangle, China, the Carlin gold deposits, Carlin, western United States, and the Muruntau-type
gold deposits in Uzbekistan. The comparative study indicates that the formation of these deposits has an intimate coupling
relation with the mechanism of the tectonic movement of modern plates. Therefore, these deposits belong to those that were
formed in the orogenic stage. They have the following similar characteristics: they are all sediment-hosted, occur in a tectonic
environment of extensional rifting nature and show the characteristics of syngenetically modified mineralization. On the other
hand, they also have noticeable differences: they are different in respect to their tectonic settings, association and structure
of orogenic belts and complexity and strength of the modified mineralization. The regional tectonic evolution and extensive
mineralization in orogenic belts are different expressions of the same continental dynamic process.
