Gamma-ray spectrometric survey for mineral exploration at Baljurashi area, Saudi Arabia

Abstract

Mineral resources exploration in the Kingdom of Saudi Arabia became an important target for the Saudi government. Nowadays, the economic vision of the country is to move away from oilbased country to multisource energy-based country. In Baljurashi area there were ancient mines for Copper, Cobalt, Magnesium, Zircon, and some other minerals. In the current study, we aim to evaluate the Baljurashi area in terms of mineral resources using the advanced technique. Consequently, we carried out ground gamma ray spectrometry survey in an area of about 50 km 2 , elevation variation ranges from 380 m to 2280 m above the sea level. We used the RS-700 system to collect the gamma ray spectrometry data. In addition, we used the existing geochemical analysis results for this area and integrated the results to map the most important minerals. The integration work indicates that the area of Baljurashi is rich in mineral resources. The mineralization zones are located in the eastern part of the area where elevation is high (e.g., east of the escarpment). We also found that these mineralization zones are structurally controlled. Important mineral maps were produced (e.g. Cu, Cr, Mn, and Zr). We highly recommend more geophysical studies to evaluate the Baljurashi area for mineral identifications and quantifications.

Digital soil mapping of lithium in Australia

“…In this study we used a complete gamma-ray survey grid where gaps in the airborne coverage were filled in using covariate machine learning (Wilford and Kroll, 2020). Gamma-ray radiometric data have been found to be a useful covariate in identifying surface processes such as sediment transport and weathering (Wilford, 2012;Wilford et al, 1997) and detecting radioactive minerals deposits and occurrences (Alhumimidi et al, 2021;Wilford et al, 2009;Dickson et al, 1996;Dickson and Scott, 1997). Total magnetic intensity (TMI), which measures variations in the Earth's magnetic field intensity caused by the contrasting content of The third factor is the soil itself, particularly, the relevant physical soil properties.…”

Internal Radiation Levels in Natural Quartz Crystals Collected from Southwestern Nigeria; Implications on Thermoluminescence Studies

“…Generally, the gamma ray spectrometric technique has been a conventional method for determination of radiation levels in any material of interest [26][27][28][29][30]. This technique has been widely employed in determination of radiation levels or radionuclide concentrations in various minerals and rock samples [28,29,[31][32][33][34][35][36][37].…”
