Abstract: The magnetic fabric characteristics and its relationship to the gold mineralization in Sawayaerdun gold deposit,Xinjiang,China,are reported here. The data given here show compression in NW-SE direction and sinistral shearing vertical to this direction. There are contraction-type and flaser-type strains occurring alternatively in NW-SE,where flaser-type strains are much more developed. Gold-bearing veins occur in en echelon,which are products of sinistral shearing. The ore vein Ⅳ,the most important gold-bearing vein,occurs in the weakly strained area close to the most strongly strained belt. Gold mineralization exists in weakly deformed rocks closely related to quartz vein,showing post-tectonic filling and crystalling of the gold -bearing fluid. Combined with the microtexture analysis of rocks in this area,Sawayaerdun gold deposit is proposed to be a shearing zone-type gold deposit,where gold bearing fluid coming from rocks in this area through pressure solution during ductile deformation,filled fractures due to tectonic compresso-shearing.
