Spacial variation mapping of aerial TC, K, eU, and eTh data according to concentration number (C –N) fractal modeling approach of A sample area in Egypt- A case study

Abstract

Geological interpretation and mapping-relying on existing airborne gamma-ray spectrometric data-were used to interpret from Gabal (Mountain) El-Bakriya area, Central Eastern Desert, Egypt. Log-log graphs and fractal concentration number (C-N) modeling technique were utilized to analyze the data and present them in various ways. Modeling according to C-N models removes the qualitative radioactive zones of TC, K, eU, and eTh. The lithological outcrops in the study area are then described in these qualitative radioactive zones. A geological map is created with C-N plots of TC, K, eU, and eTh to produce a comprehensive record of the radioactive signatures of all outcrops, which is tied to the radioactive signatures of K, which is the most well-known radioactive element for many rock formations. C-N fractal modeling shows great successes which perfectly simulate radioactive and lithological outcrop boundaries. The case study presented demonstrates the necessity of aerial gamma-ray spectrometry and fractal modeling for geological mapping and interpretation in difficult, and rocky terrains. The critical function in these situations is emphasized in this work. According to C-N fractal modeling of “K”, possibly indicating different cycles of granite eruption and formation in the study area. With the help of C-N model, radioactive break points can be created between rock types to indicate the transition from one lithology to another.
