The Triassic western European succession comprises at least four transgressive/regressive 2nd-order facies cycles which can be followed from the Boreal siliciclastic to the Tethyan carbonate settings. The exact timing of the peak transgression and maximum regression of these cycles vary slightly from basin to basin according to local physiographic conditions, tectonic behaviour and sediment supply. Up to 23 3rd-order depositional sequences are the building blocks of the 2nd-order facies cycles. They form a good framework for correlation across basins and across facies belts. A major 1st-order transgressive/regressive facies cycle also formed during Triassic times. Its lowermost and uppermost boundaries do not necessarily match with the Triassic system boundaries but, in northern Europe areas, with the Hardegsen unconformity (Late Scythian) for the lowermost one and with the Early Cimmerian unconformity (Late Norian) for the uppermost one.

Mesozoic and Cenozoic Sequence Stratigraphy of European Basins
Mesozoic and Cenozoic Sequence Stratrigraphy of European Basins - This project was designed to build a documented chronostratigraphic and outcrop record of depositional sequences calibrated across European Basins. Data on standard stages, magnetostratigraphy, and geochronology integrated with high resolution biostratigraphy calibrate the stratigraphic position of depositional sequence boundaries. Higher order eustatic sequences show a significant increase in the number identified. A good portion of the European Mesozoic and Cenozoic succession is set in a sequence stratigraphic context with a better stratigraphic record of its bonding surfaces.
