Abstract
Massive and disseminated chromite ores were collected in the Prishtina district (Kosovo) in order to characterize variations in spinel chemistry. Analyses were carried out by WD-XRES using an EPMA. Compositions of chromite in samples with distinct microstructures differ in ranges of major element concentrations. Disseminated Crspinels not only contain more Mg than massive chromite, which is related to effective subsolidus reaction with silicates during reequilibration, but they are affected by serpentinization in contrast to chromite in rich ore. Studied chromitites show cataclastic texture and "subgrains" appeared as a result of brittle deformations in the disseminated ore type. The following substitutions were verified: Mg and Mn for Fe2+, Al and V for Cr. Knowledge about differences in composition of chromite composing rich and poor ores can be useful during early stage of exploration.
