“…One of the main features of this basin is that a large proportion of the Upper Jurassic-Lower Cretaceous deposits of the northwestern area were affected by low-to very low-grade metamorphism (Guiraud and Seguret 1985;Casquet et al 1992;Mas et al 1993;Mas et al 2003) (Fig. 1A).…”

Burial diagenesis of the Upper Jurassic Torrecilla Reef Complex is recorded by a complex paragenetic sequence initiated with emplacement of ferroan calcite cements and followed by the precipitation of ferroan saddle dolomite. Ferroan calcite cements contain micro-sized dolomite inclusions (MDIs). Elemental and isotopic compositions of MDIs are virtually indistinguishable from those of ferroan saddle dolomite cements. In contrast to other scenarios for the formation of microdolomite inclusions that invoke either a magnesian calcite precursor or incomplete dedolomitization, the paragenetic relations of MDIs to their host ferroan calcite and their geochemical composition implies formation by fine-scale burial replacement of ferroan calcite by fluids associated with the emplacement of ferroan saddle dolomite.Petrographic observations and mass-balance considerations suggest that it is unlikely that Fe and Mg incorporated into ferroan dolomite could have been derived from the cannibalization of the reefal host rock. Rather, dolomitizing fluids were likely associated with the hydrothermal, low-grade metamorphic event that affected the Cameros Basin during the middle to Late Cretaceous. Interaction of these fluids with preexisting burial cements produced MDIs in the ferroan calcites.

“…These layers belong to the Huérteles Formation (Guiraud and Seguret 1985;Quijada et al 2013) of the Oncala Group (Tischer 1966) of the Cameros Basin. They were deposited on a deltaic plain influenced by tides (Quijada et al 2013).…”
