Figure S1. (a) Planar and domal stromatolites (F10) overlain by oolitic grainstone (F1) in the Gaia domain in the Querol section. (b) Line-drawing interpretation showing the boundary (black line) between T–R sequence 1 and 2. (c) Sequence stratigraphic interpretation exhibiting the key stratigraphic surfaces, facies associations and a synthetic stratigraphic section (right part). See legend for further details. Note the onlap stratal terminations of facies association F1 over the domed geometries characterizing the upper parts of the facies association F10. (d) Outcrop photograph showing flat laminated and tabular examples occurring at the base of the facies asso-ciation F10. The hammer is 32 cm long. (e) Polished slab of the basal parts of facies association F10. (f) Oolitic grainstone (facies association F1) displaying silicified ooids.

Figure S2. (a) The mounded geometry of the facies association F12 and the NE large leeward prograding geometries (facies association F15 and F16) downlapping the top of the mud-mound thrombolitic unit (F12, right part) in the Prades domain along the Brugent river, near the village of la Riba. (b) Line-drawing interpretation of the previous photomosaic showing the boundary (turquoise blue line) between T–R sequencess 1 and 2. (c) Sequence stratigraphic interpretation of the previous photomosaic showing the key stratigraphic surfaces, facies associations and geometries of sedimentary bodies. See legend for further details. Note the onlap stratal termi-nations of the facies association F4 above the subaerial unconformity with karst (black line).

Figure S3. The 150-Km-long platform to basin correlation along the Middle Triassic Catalan Basin, between Pontons and Rasquera, displaying the main facies assemblages. The data derived from the stratigraphic sections between la Figuera-Montsant and Santa Perpetua de Gaia-Pontons are projected on to the main cross-section. Note that the vertical scale has been exaggerated to show the depositional geometries and facies associations. The Prades domain is controlled by two major synsedimentary faults: the la Riba fault to the tyeast and the Ulldemolins-Gandesa fault to the west. The Gaia domain includes sections A, B and 1 to 4, the Prades domain sections 5–10, and the Baix Ebre-Priorat domain sections 11–16.

Figure S5. Sequence stratigraphic interpretation along the 150-Km-long platform to the basin transect of Fig. S4. See legend for more details. The T–R sequence interpretation is based on Embry & Johannessen (1992).

Figure S6. Restored depositional profile of the microbial-dominated T–R sequence 1 (sea level during the microbial carbonate deposition). The unconformity (MRS + TS) is used as a datum for the correlation. Accommodation of the microbial deposits in the Prades domain is controlled by a major half-graben. (a) Depositional profile shows a vertical exaggeration 9200. (b) Depositional profile shows only a vertical exaggeration 920 without stratigraphic sections. The architecture and continuity of facies distribution suggest a depositional model like a stepped carbonate ramp.
