【摘要】 河南汝阳东沟钼矿床是近几年我国发现并探明的第六个超大型斑岩型钼矿床。就矿石组构而言,结构方面以自形叶片状、鳞片状结构为主;构造方面以细脉浸染状构造为主。成矿阶段共划分为5个:(1)黄铁矿-石英脉阶段;(2)辉钼矿-石英脉阶段;(3)辉钼矿-钾长石-石英脉阶段;(4)萤石-钾长石-石英脉阶段;(5)碳酸盐脉阶段。其中最强烈矿化作用应归属第(2)、(3)两阶段。更多还原

【Abstract】 Donggou molybdenum deposit in Ruyang,Henan was discovered and proved up as the sixth ultra large porphyry molybdenum deposit in China in recent years.On the ore fabric,the structures are mainly idiomorphic foliaceous and squama;the formation is fine vein dip-dyed.Mineralization stages were divided into five parts:(1) the pyrite-quartz vein;(2) the molybdenite-quartz vein;(3) molybdenite-potassium feldspar-quartz vein;(4) fluorite-potassium feldspar-quartz vein;(5) carbonate vein phase.The most intense mineralization is in stage(2) and(3).更多还原
