[en] A combination of several exploration techniques was carried out in Al-Abter region, aiming at outlining the main characteristics of the phosphate layers in this region. The techniques used in this research are natural gamma ray well logging, gamma and alpha spectrometry. It is shown that uranium concentrations in the samples taken from the studied wells vary between 42.8 and 112.5 ppm with a standard deviation of 15.2 ppm. The P₂O₅ content varies between 20.5 and 28.31% with a standard deviation of 3.11 and the radioactive intensities vary between 150 and 275 c.p.s. The ratio of U²³⁴/U²³⁸ in the analysed samples indicates that the study region is in radioactive equilibrium. The affinity of uranium and P₂O₅ to some trace elements such as V, Sr, Cu, and Ni has been verified through studying the correlation matrix of these elements. (author)
