Usage of geochemistry of uranium and associated elements to explain the anomalous non-phosphatic radiometric halo south west margins of Saba abar, Kherbet As-Sawwaneh area. Final report on scientific research

The present research work has accomplished the whole picture of the non completed anomalous radioactive halo shown by the latest airborne radiometric survey along the extreme Southwestern corner of Saba Abar Kherbet As-Sawwaneh quadrangle. Geochemical and Carborne gamma-ray spectrometric surveys were used. The resulted radiometric maps of the radioelements U, Th, K and Ur units of the total counts assisted in achieving the completed picture of the anomalous halo towards west and north west. Thirteen anomalous spots were found in Kherbet As-Sawwaneh, Shaili and south of Abar El-Rudma Areas, especially over a cover of flint and chert blocks and stones covering the sedimentary Palaeogene rocks in close contact with volcanic basalt rocks in the vicinity of Jabal Ghurab. Upon breaking many of the chert and flint blocks and stones yellow secondary uranium mineralizations were found despite no surface indications of any mineralizations. This type of secondary uranium occurrences were never reported earlier neither in Syria no elsewhere. It is a new phenomena which deserve further investigations. In addition a few anomalous values of thorium were detected in the sedimentary rocks of the various Khebrats along the main basaltic sheet and flows. Also contamination with the isotope 136 Cs in few sampling point was still detectable in the khebrates of the area from Chernobyl fallout. (author)
