Rare earth element contents, geochemistry of soil samples between Burdur and Isparta region and assessment of their origin

Abstract

This study was carried out in 5 locations between Burdur and Isparta in the inner southern part of Isparta Bend. The study aims to determine the rare earth element (REE) concentrations in the soil samples collected from the field and to interpret the origin of the high concentrations detected. In this context, a total of 104 samples were collected from Canakli Village (19 samples), Cobanisa Village (34 samples), Kuyubasi Village (17 samples), Kuzca Village (17 samples), and Yilanli Village (17 samples) in the study field. The average ∑REE (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) concentration values of the samples by their locations were determined to be Çobanisa (821.88 ppm) > Yılanlı (723.39 ppm) > Kuzca (692.54 ppm) > Çanaklı (583.46 ppm) > Kuyubaşı (484.04 ppm). The average light rare earth element (LREEs) concentration (such as La 229 ppm, Ce 378 ppm) of the samples collected from all locations is higher than the average rare earth element concentration in the Earth’s crust. According to the Chondrite-normalized Rare Earth Elements diagram, the distributions of the rare earth elements in these 5 locations were determined to be very similar and the high concentrations were considered to occur under similar conditions or originated from similar sources. In this context, based on the idea that Gölcük Volcanism may be the source of high concentrations, the rare earth element concentrations of Gölcük Volcanism in the northwest of the zone were compared to those taken from the study area and the values were found to be consistent with each other.
