In the north-west of Greece (Pelagonic zone) during the Miocene time a specific geological evolution created some small basins where the environmental conditions have been suitable for the coal formation. The Neoalpine strike-slip movements created at the beginning of the Lower Miocene a large tectonic graben where the coal-bearing Florina-Ptolemais-Kozani basins were developed. The Neogene deposits consist of two formations with interlayer sequences of lignite. These sequences are separated in at least two distinctive series with different lithological features. Every basin contains coals with different properties. The measurements of the fault elements in outcrops and the processing and the interpretation of these data shows that in the study area there are two main fault systems with NW-SE and NE- SW directions. The former of these are considered as the marginal faults, which formed the original tectonic graben, the latter ones caused the traverse, to the general graben trend, fragmentation and formed subgrabens and small horsts, which give the actually shape of the Florina-Ptolemais-Kozani basins. These changes create the suitable conditions of marsh environment, climate and water depth for the aquatic flora growing-up, that later will supply the organic material for the lignite generation. The geological study shows that these basins are yet attractive for their supply of the energy.
