Data of Lithium from Triphylite LiFe2+PO4 Present in Conțu-Negovanu Pegmatites, in the Southern Carpathians, Romania
This study aims to describe the triphylite (LiFe2+PO4) from Li-bearing pegmatites from the Conțu-Negovanu area (Southern Carpathians, Romania). Thus, for the first time in this area, using four analytical methods, i.e., electron micro-probe analysis (EMPA), polarized optical microscopy (POM), Fourier transform infrared spectroscopy (FTIR), and powder X-ray diffraction (p-XRD), the authors have succeeded in isolating the triphylite from the isomorphous triphylite–lithiophilite series. In addition, in the Conțu-Negovanu area, two new minerals were identified and described for the first time in pegmatites from this area: Fe-rich gatehouseite and wolfeite. The use of EMPA allowed for the tentative calculation of empirical formulae for these secondary phosphate minerals.
