Platinum-group minerals and their host chromitites in Macedonian ophiolites [PDF]
European Journal of Mineralogy, 2017 Several ophiolite bodies that have been a significant source of chromium ore are located in the Vardar Zone of Macedonia. Three relatively small (maximum 15 × 4 km) bodies have been studied in detail. In the Radusa and Lojane complexes, the mantle series consisting of harzburgite and rare dunite are well preserved, whereas minor pyroxenite and gabbro ...
