Investigation of the Ünlüpınar, Eylence Yayla (Kelkit-Gümüşhane) Epithermal Pb-Zn±Au Mineralization with Gamma Ray Spectrometer Measurements

In this study, the values of Potassium (K40), Uranium (eU), Thorium (eTh) and total dose rates in 320 stations were acquired through a high-sensitivity gamma-ray spectrometer. The maps of the Potassium (K40), Uranium (eU), Thorium (eTh) and total dose rates with theirs computed ratio maps are plotted. It is seen that the high magnitude of the anomalies are located through the fault lines related to the enrichment of K by evaluating these ratio maps. High K/eTh, K/eU and Efimov F-Parameter (KeU/eTh) anomalies point out the alteration zones with transmitting hydrothermal ore solutions. It is seen that the ore zones associated with the alteration could be determined with the gamma ray spectrometry, which is fast and economics method. Also, the high amplitude areas in the Efimov F-Parameter map demonstrate the potential ore zones and might be the mine drilling points.
