ABSTRACT
The Dinaric lherzolite ophiolites (LB) differ from the harzburgite-dunite ophiolites (HDB) in increased contents of Ca, Al, and Fe, in presence of Ti, and with decreased content of Mg, pyroxenes have higher Cr and Al content, but accessory spinel is impoverished in Cr, and enriched in Al. Differences also reflect in their metallogenic signature. In the LB distinguished are small chromite and middle sized Mn-oxides primary deposits, then very big chrysotile asbestos, talc and magnesite exogenic deposits. Significant, to date non exploitable ores are related to fosterite, garnet and corundum occurrences. The HDB distinguish very big chromite and small forsterite, Mn-oxides, and copper primary deposits and middle sized chrysotile asbestos, Ni-silicates, magnesite and lateritic iron ores.
