• Resumen

  • Four units have been recognised in the temperate carbonates at the northern margin of the Campo de Dallas. The first three units (VI, 1/2, V3) could be grouped together forming a lowstand systems tract (1ST) and the fourth (V4) would represent a transgressive systems tract (TST). VI (siliciclastie sediments), V2 (calcareous breccia) and V3 (laminate ealcarenites) represent the L5T, TST and HST of higher frequence cyclicity, respectively. These carbonates can be correlated with the Azagador carbonates in the Agua Amarga Basin (50 Km to the NE) which are uppermost Tortonian/lower Messinian in age. The transgressive tendency recorded in the studied carbonates corresponds to a Tortonian/Messinian sea level rise reported on the eustatic curve of Haq et al., 1987.

    Some synsedimentary faults separate VI and V2 units from the basement, while V3 and V4 onlapped the emerged basement when the tectonic activity finished.
