This study presents the analysis of airborne gamma-ray spectrometry and aeromagnetic data to delineate the distribution of the radioactive elements and determine their anomalous zones, subsurface structures controlled mineralized zones, and 3D magnetic inversion to give a full view of basement relief. According to statistical treatment of airborne gamma-ray spectrometry measurements, the highest values of potassium and equivalent thorium associated with Nakhiel Formation are 3.2% and 12.8 ppm respectively. Meanwhile, the equivalent uranium associated with phosphate beds attains 19.1 ppm. The spatial distribution of the relatively high concentrations of eU, eU/K and eU/eTh are recorded in adjacent areas in Upper Cretaceous deposits as > 12, 25 ppm and 5 ppm for eU, eU/K and eU/eTh, respectively.

According to field measurements, the highest values of eU associated with phosphate beds and black Shale are 117 ppm and 20 ppm respectively. Meanwhile, the highest value of potassium associated with Quaternary sediments is 2.9%. Moreover, the highest value of eTh associated with Taref Formation is 16.2 ppm. The geochemical studies of collected samples from the anomalous zones showed the presence of secondary uranium in addition to rare earth elements. Meanwhile, the black shale trace elements are measured and showed high concentrations of tungsten. The magnetic data analysis is performed using tilt derivative and 3D magnetic modeling methods. Most of the deduced structures are trending in NW–SE, and NE–SW directions. The depths to the basement rocks are ranged from 0.475 km to 1.07 km below the ground surface.

这项研究提出了航空伽马射线能谱和航空磁数据的分析，以描绘放射性元素的分布并确定其异常区，地下结构控制的矿化区和3D磁反演，从而全面了解地下室地形。根据机载伽马射线能谱测量的统计处理，与纳吉尔组有关的钾和equivalent的最高值分别为3.2％和12.8 ppm。同时，与磷酸盐床相关的当量铀达到19.1 ppm。eU，eU / K和eU / eTh相对较高浓度的空间分布在上白垩统沉积物中的相邻区域记录为eU，eU / K和eU / eTh分别大于12、25 ppm和5 ppm。

根据现场测量，与磷酸盐床和黑色页岩相关的eU的最高值分别为117 ppm和20 ppm。同时，与第四纪沉积物相关的钾的最高值为2.9％。而且，与Taref形成有关的eTh的最高值为16.2ppm。从异常区域收集的样品的地球化学研究表明，除了稀土元素外，还存在次要铀。同时，黑色页岩痕量元素被测量并显示出高浓度的钨。使用倾斜导数和3D磁性建模方法进行磁性数据分析。大多数推论的结构都在西北—东南和东北—西南方向发展。地下岩石的深度范围为地表以下0.475 km至1.07 km。
