摘要
二连盆地马尼特坳陷南部EG地区是近年来新发现的铀远景区,对区内实施面积性土壤氡气测量,通过叠合平面、剖面铀矿化分析,建立EG研究区土壤氡气异常模型,圈定异常4处并实施钻探验证,结果显示,区域范围内见矿钻孔与氡气异常分布具有较明显分布关系,大部分工业矿体分布于氡气异常高值向低值过渡区边部,大致沿异常走向轴部展布。测量结果表明,EG工作区砂岩型铀矿具有进一步勘探开发的潜力。
The Engerz area in southern Manit depression,Erenhot Basin is a newly discovered uranium prospect in recent years.The large area soil radon measurement through superimposed planar and sectional uranium metallization analysis has established Engerz area soil radon anomaly model,and delineated 4 abnormal places carried out drilling verification.The result has shown that the distribution relationship between ore intersected boreholes and radon anomalies distribution is obvious.Most industrial valued ore bodies are distributed at the edge of radon anomalous high to low transition area,roughly along the strike axis extended.The measured results have shown that the sandstone type uranium deposit in Engerz area has further exploration and exploitation potential.
