Multifractal approach for delineating uranium anomalies related to phosphatic deposits in Area-3, Northern Palmyrides, Syria

Abstract

Multifractal Concentration-Number (C-N) modeling approach has been developed and applied to Airborne Gamma Spectrometry (AGS) data related to Area-3, Northern Palmyrides, Syria. The application of the multifractal approach basically aimed at separating uranium anomalies from background. The AGS technique has been applied for uranium exploration in Syria, where four radioactive parameters were recorded, T.C, eU, eTh, and K%. Log-log plots practiced on those radioactive variables indicate the presence of different uranium anomaly ranges. Those radioactive ranges have been verified and controlled by both geology field and surface spectrometric gamma sample rocks analysis. The area range of 5.37–13.20 eU includes uranium concentration more than 120 ppm, The area range of 2.95–5.37 eU includes uranium concentration of 50 ppm, and the area range of 1.40–2.95 eU includes uranium concentration of 7 ppm. Positive correlation has been consequently found between radioactive anomalous eU ranges and uranium concentrations. Such correlation indicates the importance of multi fractal approach to be extensively used as a fractal analysis-smart sampling tool in phosphate and uranium prospecting programs, where a positive correlation between phosphate content, radioactivity and uranium concentration exist.
