Data Brief. 2019 Oct 1:27:104597. doi: 10.1016/j.dib.2019.104597. eCollection 2019 Dec.


This dataset article contains mineralogical and chemical data of linarite and connellite sulfate minerals. These minerals were found included in the oxidized zones of cupriferous sulfide ores in the Fiumarella Mine, in Calabria region (Southern Italy). Linarite is a basic sulfate of copper and lead with the formula of PbCuSO4(OH)2 while connellite is a hydrated sulfate of copper with an ideal formula of Cu36Cl6(SO4)2(OH)62∙12H2O. Recently, in the mine of Fiumarella, in addition to primary minerals such as barite, galena, cerussite, anglesite, fluorite and chalcopyrite, wulfenite (PbMoO4) was also detected. Linarite consists of a prismatic bright blue crystal with a vitreous luster of micrometric size implanted upon on a matrix made up of barite. Connellite includes micrometric acicular tuft crystals protruding from matrix. Methods for obtaining the datasets include optical microscopy, micro X-ray Fluorescence and micro-Raman spectroscopy.
