Facies analysis and stratigraphy of a lower Aptian carbonate platform section (Prebetic, Alicante, Spain)
In the Racó Llobet section (Sierra Mariola, Prebetic of Alicante) crops out the Llopis Formation, dated as lower Aptian (lower Bedoulian). Six types of facies have been recognized: 1) orbitolinite facies (packstone and wackestone with orbitolinids); 2) calcarenites with grainstone texture; 3) limest...

| Resumo: | In the Racó Llobet section (Sierra Mariola, Prebetic of Alicante) crops out the Llopis Formation, dated as lower Aptian (lower Bedoulian). Six types of facies have been recognized: 1) orbitolinite facies (packstone and wackestone with orbitolinids); 2) calcarenites with grainstone texture; 3) limestones and marlstones with corals; 4) floatstones and packstones with rudists; 5) wackestone and packstone with foraminifera; and 6) mudstone with scarce fossils. These facies correspond with shallowing upward elementary cycles. In general, this section records the process of installation of a shallow carbonate platform, occurred in two progradational steps, ending with the development of a lagoon |
