【摘要】 我国天山山脉东段(新疆哈密)东戈壁超大型斑岩型钼矿床,其成矿热液蚀变作用主要表现形式为各种脉体的大量产出,石英脉及钾长石脉即为钼金属元素热液活动中的主要载体;矿床的蚀变分带共4带,由内到外为:白云母化带(绢英岩化带);钾化带;硅化带;黑云母化带。矿床成矿热液蚀变作用的区域与矿区主要工业矿体的分布区相一致。更多还原

【Abstract】 Donggebi oversize porphyry molybdenum deposit is located in the east of Tianshan ridge(Xinjiang hami) its hydrothermal ore - forming solution alteration is mainly in the form of large number of all kinds of veins occurance Quartz veins and potassium feldspar veins are the main carriers of Mo element in the hydrothermal activities.The alteration is divided into four belts from inside to outside muscovitization belt (Sericite quartzitization belt);Potash feldspathization belt;silicified belt and Biotitization belt.The oreforming hydrothermal alteration region is concordance with major industrial orebodies distribution.更多还原
