Abstract: The Mecca Quarry Shale Member from Velpen, Indiana contains abundant vanadium which occurs in solid solution within illite-rich illite-smectite (I-S) having an average content of 1.65 wt. % ...
Phosphovanadylite, whose simplified formula is (Ba,Ca,K,Na)x[(V,Al)4P2(O,OH)16]·12H2O, is a new vanadium phosphate zeolite mineral found in the Phosphoria Formation at Monsanto’s Enoch Valley Mine, So...
The crystal chemistry and structure ofthe layered lead oxychloride parkinsonite, ideally Pb7Mo09C12, have been reevaluated in the light of TEM observations of natural and syn-thetic samples and the st...
The composition and origin of vanadium-bearing clay minerals in the Jurassic (Morrison and Entrada Formations) sandstones of the Colorado Plateau are reassessed using microanalyses (microprobe and sca...
A combined application of electron paramagnetic resonance (EPR) and Fourier-transform infrared (FTIR) spectroscopies with thermal methods was used to determine the chemical form of V(IV) in a Georgia ...
An unusual vanadium chlorite precipitated during the formation of a vanadium-uranium ore deposit in the Henry Basin, southeastern Utah. The ore deposit formed by reduction and precipitation of U and V...
A unique vanadium-titanium-bearing mixed-layered clay is currently being mined as an ore of vanadium at Potash Sulphur Springs, AR. The clay contains 80% expandable portion and has both a 14.22 and 18...
