Zusammenfassung

The Triassic of the Iberian Peninsula presents three carbonate epeiric platforms (Lower Muschelkalk, Upper Muschelkalk and Imon Fm.). These three carbonate platforms are intensively dolomitized with a lower part made up of grey dolomites and an upper part of white dolomites. The white dolomites are sabkha-type dolomites and the grey dolomites reflux-type dolomites. The petrography stable isotopes and Sr isotopes of the grey and white dolomites suggest a late recrystallization process related to deep burial or hydrothermal conditions during the Jurassic-Cretaceous rifting.
