Abstract(s)

SUMMARY: The geological cartography review of the area where the Buçaco Carboniferous Basin (BCB) is located showed that its limits are either strongly tectonized or in angular discordance over Neoproterozoic and Paleozoic lithology’s. Mesocenozoic sediments mapped also settle limits with the BCB units. At the eastern limit of the basin, a normal fault generated in an extensional regime was identified, active during the deposition of lithostratigraphic units dated from the Gzhelian, while at the opposite limit, a tangential compressive tectonic was identified (ENE-WSW direction), with material transport to ENE, posterior to the predecessor event. The described tectonic episodes are associated with the final stages of the Variscan Orogeny.
