摘要: Abstract The Zhibo and Chagangnuoer iron ore deposits occur at the same volcanic edifice are situated along eastern segment of Awulale Iron Metallogenic Belt in Western Tianshan orogen China. former deposit is exposed near caldera latter lies on northwestern flank structure. mineralization, texture, bodies structures, trachytic to trachy andesitic host rocks geological characteristics indicate a magmatic source for oxide mineralization. This supported by observation that vast majority magnetites have δ 18 O values between >+0.9‰ (
