中文摘要:
      河南省卢氏县夜长坪钼矿床是东秦岭地区大型斑岩—夕卡岩型钼矿床之一。该矿床受近东西向和北北东向棋盘格式断裂构造复合控制,矿体赋存于深部花岗斑岩体内及外接触带夕卡岩中。文章利用矿区采集的代表性极高的辉钼矿样品的Re-Os同位素测年分析数据,经相关综合分析研究后,推断矿床成矿物质主要源于下地壳,同时混有少量幔源组分;界定矿床成矿系统形成于晚侏罗世—早白垩世中国东部构造体系大转化时期。
英文摘要:
      The Yechangping Mo deposit,Lushi country,Henan Province,is one of large-scale porphyry-skarn type of Mo deposit in the famous Eastern Qinling Mo metallogenic belt,which is mainly compound controlled by the EW-trending and NNE-trending fault. The deposit is hosted in the skarns,and porphyritic granite which was seated in the depth. The authors makes use of year analytical data which represent the high representative molybdenum ore sample of the Re-Os isotope, through the correlation analysis,predict that ore forming matenials is mainly derived from the lower crust and mixed with the component of the mantle,and the molybdenum mineralization occurred in the period of late Jurassic-Early Cretaceous,which formed when the tectonic transformation predominated was defined. 
