Uranium Minerals in the Radlovac Series Metasediments at Mt. Papuk, Croatia

摘要

Applying a combination of different methods – X-ray diffraction, scanning electron microscopy, gamma-spectroscopy and X-ray spectroscopy, a suite of uranium minerals, meta-torbernite, meta-uranospinite and meta-zeunerite was identified in metasediments of the Radlovac series at the Mt. Papuk area, Croatia. The accessory minerals galena, zircon, rutile, chalcopyrite and cuprite, as well as an unidentified Ni-bearing phase are also present. The mineral assemblage indicates a sequence of epigenetic and supergene processes affecting the Radlovac series.
