Deciphering Paleogene platforms from a “Lost Domain” in the Western Neo-Tethys
According to classical literature, two Paleogene platforms developed along the northern and southern margins of the Neo-Tethys Ocean. Similar platforms have been recognized on the southern margin of a “lost domain” consisting of an independent microplate known as the “Mesomediterranean Microplate” (MM) in the westernmost Neo-Tethys Ocean. This microplate underwent tectonic dismantling and drifting during […]
Paleogene evolution of the External Rif Zone (Morocco) and comparison with other western Tethyan margins
The Paleogene evolution of the NW margin of the African Plate (Western External Rif Zone) was studied by means of multidisciplinary analyses of twenty-one stratigraphic logs, including tectofacies recognition, petro-mineralogical results, and thicknesses analysis. Four stratigraphic intervals were recognized separated by three unconformities coarsely aligned with the Cretaceous–Paleogene, Eocene–Oligocene and Oligocene–Miocene boundaries, respectively. Tectofacies appear from the late Ypresian […]
Tectonic breakup in the Eastern Betic zone
Six Paleogene-Aquitanian successions have been reconstructed in the Alicante area (eastern External Betic Zone). The lithofacies association evidences “catastrophic” syn-sedimentary tectonic processes consisting of slumps, mega-olisthostromes, “pillow-beds” and turbiditic deposits (Figure 1). This kind of sedimentation is related to unconformity surfaces delimiting sequence and para-sequence cycles in the stratigraphic record (Figure 2). The data compiled […]
Paleogene sedimentary evolution of the Alicante Trough
A new work to illustrate a changes in the evolution of the Alicante Trough located to the southeastern part of the sudiberian paleomargin and north to the supposed elevated sea floor forming a marine platform. Here the link to the work in Repository of the UA. The Paleogene Alicante Trough of the South-Iberian Margin (External Betic […]
