  1. Ni-laterites, Ni in soils in east Albania Simplified tectonic map of central part of Albania (Hoxha, 2001). B: Distribution of ophiolites along of the Balkan Peninsula (after Bortolotti et al., 1996).

  2. Ni-laterites, Ni in soils in east Albania Geological map of the Prrjenas intramontane basin (from the Geological Map of Albania 1:200,000). Noticeable that the chain of Ni-laterite deposits follows always the boundary of serpentinite and the cover Cretaceous limestone.

  3. Ni-laterites, Ni in soils in east Albania Panoramic view of the Prrenjas intramontane basin with indication of the position of the village, the mines and the typical lithologies of the major chines.

  4. Ni-laterites, Ni in soils in east Albania Synoptic profiles of major types of the Ni-laterite deposits of the Balkan Peninsula. Compiled according to: Ivanov, 1960; Augusthitis (1962); Arkaxhiu and Kici (1990); Skarpelis et al., 1996; Skarpelis, 1997; Eliopoulos and Economou-Eliopoulos, 2000; Peci and Grazhdani, 2001 and field observations of ID in 2004. (a)-(d): deposits of Cretaceous age. The first column (a) represents the most typical profile; the laterite deposited more-or-less autochtonously on the weathered ultrabsic rock. (b): The lateritic material was redeposited and covers slightly- or unwathered ultrabasite. (c) & (d): The lateritic material was resedimented on Mesozoic limestone. (e): the footwall and henging wall of the deposit is bordered by faults, the stratigraphic age of the cover sequenci is unknown. (f): Paleogene cover with alternating deposition of lateritic and siliciclastic material. (g): Deposits in the Miocene sequences.

  5. Ni-laterites, Ni in soils in east Albania Major stages of post-sedimentary overprint of the laterite deposits of the Balkan Peninsula and the Greek archipelago.

  6. Ni-laterites, Ni in soils in east Albania Geological setting of laterite ore deposits of the Edessa are, Greece a: Messimeri; b: Vrita; c: Flamuria (from Michaildis, 1990). These profiles show how different are the stratigraphic successions even within a small area further these profiles are representing well the characteristic tilting and thrusting.

  7. Ni-laterites, Ni in soils in east Albania The base of the Bitincka laterite layer shows a complex geometry, partly due to the deposition on the irregular surface of the serpentinite, but a young faulting has also some role.

  8. Ni-laterites, Ni in soils in east Albania The immediate cover sequence in Bitincka.

  9. Ni-laterites, Ni in soils in east Albania Ni-silicate veins in the Ni-laterite.

  10. Ni-laterites, Ni in soils in east Albania Serpentinite pebbles and clasts in protolaterite – Kurbneshi, northern Albania.

  11. Ni-laterites, Ni in soils in east Albania Limestone fragments in Ni-laterite – Katjeli.

  12. Ni-laterites, Ni in soils in east Albania Ni-laterite mines and dumps are throning above the settlements.

  13. Ni-laterites, Ni in soils in east Albania Microscopic reflected light image of a weathered chromite grain (gray) which is replaced along cracks by hematite (white). Width of picture is ca. 270 µm (from Augustithis, 1962).

  14. Ni-laterites, Ni in soils in east Albania from Michailidis et al. (1985)
