灵泉火山盆地铀成矿条件分析

Analysis on Uranium Metallogenic Conditions of Lingquan Volcanic Basin

灵泉火山盆地位于著名的额尔古纳—克鲁伦北东向火山岩铀成矿带中南段,与俄罗斯斯特列措夫铀矿田、蒙古多尔诺特铀矿田处于同一矿带上。通过多年在该盆地的地质工作,在盆内发现了众多的铀矿化异常点(带),呈现良好的找矿前景。在详细论述了盆地的基底、盖层、火山岩岩石化学和热液蚀变等特征的基础上,分析了盆地的铀矿化特征和成矿条件,认为该盆地是寻找火山岩型铀矿的有利远景盆地,指出了盆地南部是下一步工作的重点地段。

Lingquan volcanic basin is located in the mid-southern segment of known Rrguna-Kelulun Eastnorthtrending volcanic rocks uranium metallogenic belt, it is on the same belt with Telechuf Field of Russia and Durnuot Field of Mongolia. There are many uranium mineralized and anomaly occurrences （belts） with great prospect in this basin. Based on the characteristics of the basement, covering, volcanic rocks and alternation of the basin, the uranium mineralization and metallogenic conditions is analysed, it is concluded that this basin is a favorite one for prospecting volcanic rock type uranium deposit and the southern part of the basin is the target for the near future survey.
