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.
