摘　　要：In this paper an integrated geological and geochemical comparison is made of Carlin-type and Carlin-like-type gold deposits in the region of South Qinling with their associated hydro-thermal sedimentary lead-zinc deposits, the Carlin-type deposits in the Yunnan-Guizhou-Guan-gxi gold triangle, China, the Carlin gold deposits, Carlin, western United States, and the Mu-runtau-type gold deposits in Uzbekistan. The comparative study indicates that the formation ofthese deposits has an intimate coupling relation with the mechanism of the tectonic movement ofmodern 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 tectonicenvironment of extensional rifting nature and show the characteristics of syngenetically modifiedmineralization. On the other hand, they also have noticeable differences: they are different inrespect to their tectonic settings, association and structure of orogenic belts and complexity andstrength of the modified mineralization. The regional tectonic evolution and extensive mineraliza-tion in orogenic belts are different expressions of the same continental dynamic process.
