Abstract

Mineralogical features and compositional data on bournonite from epithermal vein deposit of Văratec, Băiuţ mine field in the Baia Mare district, Romania are presented. Bournonite is disposed in quartz matrix or it is associated with chalcopyrite and tetrahedrite. SEM images demonstrate the absence of intergrown derivates with distinct compositions. Variations of chemical composition of bournonit have been recorded using electron probe microanalyses. The negative correlation of Sb – As contents indicates a substitution process between the two elements and the presence of limited solid solution towards seligmanite.
