Abstract
The R anovo deposit is a unique example of metamorphosed lateritic Fe–Ni deposits in the well�
known Vardar ophiolitic belt of the Balkans, where Fe–Ni mineralization is a product of the Early Cretaceous
lateritic weathering mantle after Jurassic ultramafic rocks subsequently redeposited into the Cretaceous shal�
low�water marine basin. As a result, a layer of Fe–Ni ore 30–50 m thick with an average Ni grade of ~1% was
formed at the R anovo deposit; this layer is traced for more than 4 km along the strike and 500 m down the
dip. At the end of the Late Cretaceous, intense Alpine tectonic faulting and folding resulted in overturning of
the initially horizontal ore layer, which is now nearly vertical. The most abundant fissile hematite ore contains
0.70–1.27% Ni, whereas the economically most important massive hematite ore with 0.93–1.49% Ni occurs
locally. The major Ni�bearing minerals are magnetite, hematite, chromite, sulfides, talc, chlorite, amphibole,
and stilpnomelane.
