Abstract

Sierra de la Estrella outcrops belong to the Sierra del Castillo Unit, which is defined in the Guadiato Area, SW Spain, where sedimentation occurred during the Late Viséan. The Guadiato Area is located on the boundary between the Ossa-Morena and Central Iberian structural zones, in the southwestern Iberian Peninsula, where Lower Carboniferous outcrops are common. The stratigraphic succession from Sierra de la Estrella is dated precisely by means of foraminifers (Zone 15). The studied rocks are interpreted as having developed on a storm-dominated ramp. Microbial buildups occur interbedded between tempestites and marls. Two main types of mud mounds have been distinguished: large tabular and smaller dome-shaped mud mounds, which were developed in a middle-ramp setting.
