| 为查明二连盆地苏尼特右旗地区HFU-39、HFU-40航放异常的铀成矿情况，本文在分析异常区区域地质资料基础上，采用地质剖面测量、地面伽玛总量测量、伽玛能谱剖面测量、土壤氡剖面测量及岩石化探取样分析综合方法，对HFU-39、HFU-40两个异常进行查证及评价。查证结果显示异常呈团块状展布，地面伽玛能谱测量铀含量最高达w（U）=135×10-6，岩石化学分析铀含量最高达w（U）=256×10-6，该区域氡异常突出；综合异常查证结果和对二连盆地泥岩型铀矿化的形成环境分析，指出了该区的下一步铀找矿方向。 |
| 英文摘要: |
| In order to find out the uranium mineralization in Suniteyouqi area of Erlian Basin this paper uses a integrated method of geological profile survey, ground total radioactivity survey, radioactivity spectrum profile survey, soil radon profile survey and rock geochemical exploration on basis of on the analysis of regional geological data to verify and evaluate the anomaly HFU-39 and HFU-40. The result of verification shows that the anomalies are distributed in masses. The maximum ground gamma energy spectrum-measured maximum uranium content is 135×10-6 and chemical analysis of uranium of rock samples w(U)=256×10-6. Regionally the radon anomaly is prominent. Then the anomaly verification is combined with the analysis of formation environment of mudstone type uranium mineralization in Erlian Basin to point out the next uranium prospecting direction in this area. |
