Some secondary uranium minerals from San Leone (Sardinia), collected in proximity of the magnetite deposit are described. They are phosphuranylite, parsonsite, sabugalite, saleeite and metasaleeite, metatorbernite, and alpha - uranophane. The identification was carried out by means of diffractometric and spectrochemical methods, with the aid of optical studies. Many samples of sabugalite and saleeite show a very imperfect reticular lattice and strong optical anomalies with 2V up to 70 deg . The absence of As and the scarcity of Ca in those minerals are emphasized and discussed. Parsonsite, metasaleeite and sabugalite are new minerals for Italy; saleeite and phosphuranylite have been identified for the first time. (auth)
