Abstract:
The continental rift tectonic belt of western Beishan in Xinjiang province was occurred on the basis of Archean-Proterozoic layers of Tarim block, bearing a block-rift-block,tectonic pattern, which along NEE-NWW had ever underwent 3 distinct large-scale convergence and disconvergence events as well as evolution model changed from South to North in ∈,O-S、C-P, respectively. There were many distinct types of Au ores exposed in the Pelaozoic deposits, and contained many of Au-metallogenic subzone. The discussion presented in this paper is the Pelaozoic Vlevel Au-Cu metallogenic regularity of Beishan in Xinjiang province1 For ore-hosting rock types it can divide in to six types,the ore-bearing rocks were composed of 4 distinct types:quartz vein,cataclastic alteration,quartz vein and cataclastic a lteration, in termediateacid magmatic hydrothermal,among of which the quartz vein and cataclastical teration was a domination. The ore-controlling factors were stratig raphy formation,lithological formation(volcanic rock, clastic rock and Ca rbonaceous series),ductile-brittle fracture,magmatic rock and so on,the first three types are mainly. Mineralization epochis Hercynian,Indo-Chinese and Himalayan,and the tectonic movement is synchronize with the Hercynian.
