| Sumario: | The lower Paleogene stratigraphic successions of the Talembote upper Ghomaride Unit represent an interval of age going from the (middle?) Ilerdian to the early Bartonian, showing a transgressive sequence interrupted by intermittent sedimentary gaps, which are indicated by surfaces of discontinuity. These sediments correspond essentially to carbonatic facies with benthic foraminifers deposited in a shallow platform that was maintained probably until the late Lutetian. The abrupt rupture of this platform allowed, during the early Bartonian, sedimentation of pelagic to hemipelagic facies in a bathyal sedimentary environment. Later, the sudden interruption of the sedimentation in the early Bartonian, indicated by a paleosoil, may be better explained by tectonic reason than eustatism taking into account many actual geodynamic reconstructions |
