Basculation

This twofold movement upon the centre, - this basculation, - has succeeded in cases where the elevation, singly, has been unsuccessful.

And during the Middle and Upper Carboniferous the basculation of the palaeozoic deposits was produced forming nowadays a monoclinal system in the northern border of the Tinduf depression […]

This elongated distribution is unlikely to have been produced by any tectonic cause, either continental drift or local basculations.

Flexural basculation towards the south, in combination with the main sediment source being in the Betic cordillera, determined an axial (along-strike) fluvial drainage running along the northern boundary of the sedimentary basin […]
