Las cuatro discontinuidades de orden mayor que se reconocen en el conjunto de la cuenca son: intracarixiense (controlada por la tectonica regional y mas secundariamente por el eustatismo), la del limite Lias-Dogger (esencialmente eustatica), la del limite Dogger-Malm (eustatica y tectonica) y la finijurasica (tectonica y eustatica).
