Gamma ray spectrometry method in detecting the low sulfidation type epithermal Au+Ag mineralization (Gümüshane, Ne Turkey)

Abstract

The gamma ray spectrometry has been widely used in mineral exploration, geological mapping and environmental radiation monitoring.The Eastern Pontide orogenic belt, which constitutes an important part of the Alpine-Himalayan system, hosts various types of economic mineral deposits of massive sulfide, porphyry copper, skarn, and epithermal vein-type ore deposits. Potassium is generally the most useful pathfinder element for gold mineralization zones. High level K/eTh, K/eU and Efimov F-Parameter (KeU/eTh) anomalies showed the alteration zones transmitting hydrothermal ore solutions to the surface. As a result, the gamma ray spectrometry, which is fast and economics method, might be used for estimation of prospective Au ore zones associated with the K alteration. © 2017 European Association of Geoscientists and Engineers EAGE.
