Abstract:

The Au-Cu ore deposit Kateba'asu is one of recently discovered large gold-copper deposits in western Tianshan Mountains in Xinjiang.The authors present a research result on geological characteristics,mineral composition and texture & structure of ores, wall-rock alteration,mineralization periods of and the ore-controlling factors of the Kateba'asu ore deposit.The geological,mineralogical and petrological studies of the deposit indicate that ore bodies are mainly occur in the monzogranite,and controlled by both the jointed structural system of fracture zone,and the contact zone of intrusion and marble strata.The ore bodies in jointed system are vein-shaped,with ore structures such as fine veins,veinlets-disseminated,and spotted massive,and the alterations are mainly potash feldspathization,silicification,sericitization and chloritization. The altertations are grossularization,diopsidization,tremolite-actinolitization and epidotization.There are two phases of mineralization in the deposit,which are related to monzogranite and diorite-dyke respectively and superposed in space to a certain extent.The deposit is controlled by strata,structure and magmatism,and is the type of Skarn-fracture zone altered deposit.The research results may provide the direction for the regional prospecting.

Key words: Skarn-fracture zone altered rock type, Au-Cu ore deposit, Kateba'asu, western Tianshan
