| 摘 要： | 二连盆地是一个大型中新生代产铀盆地,近年来在该盆地寻找可地浸砂岩型铀矿取得了重大突破。本文通过系统研究和找矿成果分析,建立了二连盆地找矿目标层确定的依据,提出二连盆地主要找矿目标层为赛汉组,次要目标层为二连组、伊尔丁曼哈组,找矿类型为层间氧化带型（含潜水-层间氧化带型）;进一步总结出可地浸砂岩型铀矿的找矿判据,分析了二连盆地的找矿前景和找矿方向,指出巴音宝力格隆起带的南缘（乌兰察布坳陷北部和马尼特坳陷）是二连盆地寻找可地浸砂岩型铀矿最为有利的远景区。

| Abstract: | Through the contrast study of petrography,micro thermometry and laser Raman ingredient analysis of fluid inclusion,this paper has verified the basic nature of ore-forming fluid（temperature,salinity and ingredient）in daqiaowu uranium deposit,discussed the origin of the ore-forming fluid with its structure character and geology-geochemistry character.The testing results indicats that ore-forming temperature of this deposit is between 200℃and 250℃ in main metallogenetic period,which belongs to middle temperature hydrothermal.The ore-forming fluids are of middle-high salinity and rich in valatility suchas CO2,H2,CH4.To sum up,the deposit mineralization process should be affected by the deep fluid primarily,and the ore-forming fluid is mainly the mantle fluid. |
