中文摘要:
      花海盆地位于甘肃省走廊盆地群西缘,是中国深部铀资源勘探的重要潜力区之一。根据对土壤氡气浓度信息提取和野外勘探钻探成果分析,花海盆地土壤氡浓度可分为东部正常场-偏高场氡晕和西部偏高-高场晕氡晕;下白垩统下沟组(K1x)砂岩层段为本区铀矿化有利层位,建议在西部、南部土壤氡气偏高-高场晕氡晕过渡带追索层铀矿化带,寻找有利靶区。
英文摘要:
      Huahai basin is located in the western margin of Corridor basins in Gansu Province, and is one of the important potential areas for deep uranium exploration. Based on the extraction of radon gas in soil and the information of the field exploration, it is considered that the soil radon concentration in Huahai basin can be divided into normal to high in the east and even higher in the west. The Lower Cretaceous sandstone of Xiagou Formation (K1x) is the target reservior of uranium deposits in the study area. The authors suggest that the favorable target is in the transition zones and uranium mineralization belt with higher Radon levels in the west and south of the area.
