The Mesozoic-Tertiary cover bed presents greater lithological diversity, although the areas closest to the axis have a predominance of limestone, dolomite, marl, marly limestone, sandstone, clay--with and without evaporites--, lutite, conglomerate and turbidite (Fig.
In the Central Baltoscandian Confacies Belt this event coincides with coarsening of the calcareous sediment from lutite to fine-grained shelly sand (Jaanusson 1982b, pp.
Especially, phyllosilicates with properties of clay minerals in the sediment-forming processes and in the argillosphere affected by post-depositional processes are a great theme, which attracts attention of geologists and other experts examining argillaceous and lutite accumulations developed through the geological history of the Earth.
The soils of the region are basically a rocky substrate of Upper Cretaceous lutite or siltstone.
The Basement sequence is overlain by deposition of sedimentary packages, where the calcareous shales, lutite, calcilutite and evaporite levels reported in the wells were found intercalated with bioclastic calcareous layers that would function as seal rocks.
In dark lutite layers locally associated with this facies, total organic carbon contents (T.
4), which comprises a 106 m thick basal lutite sequence dominated by red and green lutites, with some sandstone alternations deposited by fluvio-alluvial processes.
