Características mineraloquímicas e implicancias genéticas de la vesubianita del skarn Loma Marcelo, sierras australes de Buenos Aires
Resumen
The vesuvianite from Loma Marcelo skarn, Sierras Australes of Buenos Aires province, was studied by petrography, X-ray diffractometry and energy-dispersive X-ray spectroscopy that allowed establishing P4/nnc crystal symmetry and the presence of fluorine. These findings point out a formation temperature around 500 °C and CO$latex ^{_{2}} $mole fractions higher than those for the stability field of the association vesuvianite + wollastonite.
