摘要
Abstract
In this paper,the authors summarized the metallogenic model of the Feimo Cu-Mo polymetalic deposit on the basis of geological,geochemical and isotopic geochronological characteristics of the ore deposit.The S,Pb isotopes of rocks and ores show that the metallogenic material was derived from deep mantle source,with the addition of a certain amount of crust-derived material at the late stage.H,O isotope characteristics show that the ore-forming hydrothermal fluid originated from ascending magmatic hydrothermal solution in combination with mixed hydrothermal solutions dominated by permeable meteoric water.Statistic Re-Os isotope dating of the deposit yielded (47.81 ± 0.71) Ma.The main mineralization occurred in the post-magmatic hydrothermal stage of late Dapijia rock mass magmatic emplacement.The ore deposit genetically belongs to the sedimentation-meta-morphism-magmatic hydrothermal solution superimposed deformation type Cu-Mo polymetallic deposit.The mineralization of the deposit was characterized by long period,multi-phase,poly-source,poly-stage and multigenesis,and the ore-forming process experienced the sedimentary locating stage of Proterozoic,regional meta-morphism-reformation-enrichment stage of middle-late Proterozoic,and subversive reformation superposition enrichment stage of Himalayan period.关键词
