3D modeling and visualization of geological structures with Python.
Interactive 3D HTML models and visualizations of geological structures derived from classic surface geological information have been developed, for the first time, in a Python environment, using the key case of the tectonic Mula sheets in the Betic Cordillera (southern Spain). These models were performed through several steps: a geological 2D sketch map, creating equispaced […]
The Miocene sedimentary cover of the Mula-Gebas Basin (South Spain)
The Sierra Espuña and the Mula-Gebas intramontane basin, SE Spain, represent the Internal-External Zone Boundary (IEZB) of the Eastern Betic Cordillera. The Miocene infill of this basin seals the IEZB and is mainly derived from the Internal Zone. This deposition is coeval with a Late Miocene volcanism. Therefore, the study of these sediments is crucial […]
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 […]
Multicostate terebratulides (Brachiopoda, Early Jurassic) in the westernmost Tethys Ocean
Early Jurassic multicostate Terebratulida are substantiated in the Subbetic Domain and reported in the Iberian Range for the first time. Records of this clade are revised in the peri-Iberian platforms (Subbetic, Iberian Range, Gibraltar, North and NE Spain, Lusitanian basin) in order to evaluate their global pattern distribution across the Tethys Ocean. After a new […]
Koudiat El Madene unit (Kabylian “Dorsal”, Algeria) and its correlation
The Koudiat El Madene Unit (Arba Massif) belongs to the Kabylian “Dorsal” (Algerian Internal Zone). The stratigraphy and tectonic structuring of the area is equivalent to the western Moroccan Internal Rif and its counterpart in the Spanish Internal Betic Cordillera. In fact, all these chain segments are due to a common Cenozoic geodynamic evolution related […]
History of western Tethys Ocean and the birth of the circum-mediterranean orogeny
A broad region of Mesozoic to Cenozoic tectonism along the western and central Circum- Mediterranean (CM) margins, from southern Spain (Betic Cordillera) to the northern Morocco (Rif) and Italy (Apennines), includes huge volumes of sedimentary record since the Late Paleozoic. These sediments are contemporaneous and related with the fragmentation of the Pangean supercontinent due to […]
Eocene Gravity Flows in the Betic Cordillera, Spain
In the Betic-Rif Cordilleras, recent works have evidenced the existence of well-developed Eocene (Ypresian-Bartonian) carbonate platforms rich in Larger Benthic Foraminifera (LBF). Contrarily to other sectors of the western Tethys, like the Pyrenean domain in the North Iberian Margin, where these platforms started in the early Ypresian (Ilerdian), in the Betic-Rif chains, the recorded Eocene […]
Geosciences, Volume 15, Issue 3 (March 2025)
The march issue of the Geoscience journas has a cover story dealing with the newly published paper in that issue by Tosquella et al. (2025) of our group. In the Betic-Rif Cordilleras the Eocene platforms started in the Cuisian after a gap including the Ilerdian. An Eocene succession with gravity flows consisting of turbidites and […]
Paleocene-Eocene evolution of the Prebetics (South Spain) and comparison with other western Tethyan margins
Thirteen Paleocene-Eocene sections have been studied along the Prebetic Domain (South Iberian Margin) in the Alicante, Murcia, Granada, and Jaen Sectors. The sedimentary realms (mostly consisting in 15 shallow marine Lithofacies) and the tectono-sedimentary evolution were characterized. Three informal stratigraphic units were proposed and dated with planktic foraminifera, calcareous nannoplankton, and Larger Benthic Foraminifera (LBF): […]
Detrital signatures of the Ghomaride Culm cycle in Northern Morocco
The Carboniferous detrital suites of the Ghomaride Subdomain (Rif Cordillera, N Morocco) has been undertaken in order to obtain paleogeographic and paleotectonic constraints. Microconglomerate and sandstone samples from eight sections belonging to four sectors were petrographically studied. This northern Gondwana domain was part of the Paleo-Mesomediterranean Plate, located between the Iberian-French Plates and the African […]
