The first four were deposited along a steep margin. They display down-lapping and off-lapping geometries, and are characterised by poor reef-framework development, large volumes of reworked corals and transported sediment, and limited growth of micro-encrusters. In contrast, deposition of the fifth and younger accretionary units occurred on a shallow platform without a pronounced slope where coral reefs grew in a shallow protected environment. The main features of these reefs are an absence of reef-slope facies, a high proportion of preserved framework elements, relatively low volumes of intra-reef sediment, high proportions of terrigenous material, and abundant micro-encrusters and microbialites. These reefs were protected from storm waves by long-shore sand bars, which also protected a very shallow lagoon during the last stage of sedimentation. The early Kimmeridgian was a period of rising global sea level, a trend apparent across other portions of the Iberian Basin. However, geometry and sedimentary evolution of the Torrecilla Reef Complex is consistent with those of off-lapping reefs that develop during sea-level fall. Thus, we conclude that down-stepping geometries and evolution to progressively shallower environments within the Torrecilla Reef Complex occurred as a result of a tectonically forced regression.engjournal article1879-0968https://doi.org/10.1016/j.sedgeo.2005.09.007restricted access551.7: 551.762(46)Carbonate platformCoral reefForced regressionTectonismEarly KimmeridgianIberian BasinGeología estratigráfica2506.18 Sedimentología
