Uranyl phosphates and associated minerals in the Koprubasi (Manisa) uranium deposit, Turkey

The Koprubasi uranium deposit is the largest known uranium deposits in Turkey. Uranium mineralization is hosted in Neogene fluvial sediments that consist of predominantly sandstone and conglomerate inter layered with siltstone, claystone and mudstone. Sediments were primarily derived from metamorphic rocks adjacent to the basins of deposition, with some volcanic contribution in the form of tuffs. The sandstones and conglomerates are the most widespread sediments within the study area and host the majority of the U ore.
