Article
Mixed siliciclastic-carbonate deposits accumulated in several satellite sub-basins at the southern margin of the Guadalquivir Basin, the foreland basin of the Betic Cordillera (S. Spain). The prevailing coarse-grained sediments and deposition in shallow-water settings make it difficult to establish the precise age of the complete successions. For t...

Sea-level fluctuations and changes in sediment grain size are widely thought to be the main factors controlling carbonate platform slope geometries. Two successive clinoform bodies from the Upper Miocene Cariatiz carbonate platform (SE Spain) were selected to analyze geometry and facies distribution in relation to sea-level oscillations. Facies occ...
Article
General facies models developed for modern and ancient Mediterranean temperate-water carbonates in the last two decades have shown that the style of deposition on outer-ramp, slope, and basin environments in low-energy areas such as the Mediterranean Sea differs overall from that of high-energy open-ocean areas, given the wider variety of smaller-s...

Agglutination of particles is a major process involved in microbial dome formation. Early lithification by biogenic precipitation or early cementation is also essential for dome accretion and preservation. Although it is possible for agglutinated grains to be siliciclastic, reports of siliciclastic microbial domes are scarce. Early lithification of...

The Messinian record of marginal Alboran basins, such as the Sorbas Basin in southern Spain, consists of a shallow-marine succession with intercalated evaporites. The pre-evaporite sequence comprises a bryozoan-bivalve, temperate-carbonate unit overlain by tropical carbonates. The latter, in turn, consists of two superimposed units: a bioherm unit...
Article
The result of sea level fall at the margins of the Mediterranean during the Late Miocene `Salinity Crisis' was the creation of an extensive erosion surface. However, the shape of this `Salinity Crisis' unconformity reflects local factors and in turn significantly determined local conditions during subsequent reflooding. At Sorbas, in southeast Spai...
