%X The Devonian succession between the Guadiana and Guadalquivir valleys in the Obejo-Valsequillo Domain comprises more than 600 m of shale and sandstone with some interbedded limestoneand marl. The most complete reefal sequences of the region are exposed in the Guadámez-2section, which is located on the western bank of the Guadámez River, near Zalamea de la Serena. Itconsists mainly of shale and calcareous shale in its lower part and shaly, skeletal and reefal limestonein its upper part. Conodont and brachiopod data indicate that this section spans the interval fromthe Lochkovian to at least the upper Emsian. Eight microfacies types have been identified in thecalcareous facies: A, brachiopod-echinoderm wackestone/packstone; B1, echinoderm grainstone;B2, echinoderm-bryozoan grainstone/packstone; C, echinoderm packstone; D, tabulate coralrudstone; E, brachiopod wackestone/packstone; F, brachiopod grainstone/packstone; and G,stromatoporoid and tabulate coral boundstone/rudstone. Microfacies A, B1, C, E and F representa sequence of environments from middle platform (A) to tidal flat (F), including shoals (B1) andshallow platform facies. Microfacies B2, D and G represent the development of patch-reefs super -imposed on the shoals.
