The interpretation of aerial gamma ray spectrometry in term of geological and environmental analysis is undertaken herein through applying a specific methodology including different radioactive and statistical techniques for characterizing the sedimentary and environmental conditions of the Al-Rassafeh Badyieh (Area-2), Syria. The radioactive technique uses the uranium favorability index (U) and alteration(F) parameters, that are evaluated through analyzing the relationships between eU, eTh, K and their ratios (eTh/eU, eU/eK, and eTh/eK) for the nine scored lithological units already determined in the study area. The statistical technique applies the non linear multifractal approach with the concentration-number model (C-N) and log-log graphs to differentiate between different radioactive ranges of U and F parameters. The radioactive element re-distribution, the favorability as regards uranium potentiality, and the degree of uranium remobilization are separately estimated and documented for the nine scored lithological units. Those units show a limited uranium remobilization and redistribution. The sedimentary and environmental conditions of the Area-2 are clarified through analyzing the eTh/eU ratio, where marine and continental environments are indicated in the study region.
本文通过应用特定的方法,包括不同的放射性和统计技术,对叙利亚 Al-Rassafeh Badyieh(区域 2)的沉积和环境条件进行了航空伽马能谱解释。放射性技术使用铀有利性指数(U)和蚀变(F)参数,通过分析研究区域中已确定的 9 个评分岩性单元之间的 eU、eTh、K 及其比值(eTh/eU、eU/eK 和 eTh/eK)之间的关系来评估这些参数。统计技术应用非线性多重分形方法和浓度-数量模型(C-N)以及对数-对数图来区分 U 和 F 参数的不同放射性范围。分别对 9 个评分岩性单元进行了铀元素再分配、铀潜在有利性以及铀再迁移程度的评估和记录。这些单元显示出有限的铀再迁移和再分配。通过分析 eTh/eU 比值,阐明了该区域的沉积和环境条件,表明研究区域存在海洋和大陆环境。
