Article
This study combines published isotope data (223 samples) with new data (153 samples) on the δ³⁴S and δ¹⁸O composition of Ca-sulfate rocks (anhydrite and secondary gypsum) accumulated in eastern Iberia during the Middle Triassic to Early Jurassic. The δ³⁴S mean values of the evaporite units reveal the following trends: a decrease from the lower Anis...

Cartographic, stratigraphic and structural studies in the Alt Palància and Manzanera areas indicate that the Middle-Upper Triassic successions entirely belong to the 'Mediterranean type of Triassic'. The two carbonate unbits of the Muschelkalk facies have carbonate-marl alternations both at the base and at the top. The palynological study of clayst...
Article
Volcanic rocks of the Zamoranos Formation exposed in the Betic Cordillera of southern Spain reveal Late Triassic CAMP volcanism extending from southwest to southeast of the Iberian massif. Comparison with volcanic rocks from the Upper Triassic of the Algarve region in Portugal enables correlation between these different magmatic provinces based on...
Article
Much of the eastern sector of the Mesozoic Iberian basin belongs to the ‘Mediterranean type’ Triassic. This type is characterized by a Middle Triassic stratigraphic record comprised of two carbonate Muschelkalk units (lower and upper) separated by a detrital-evaporite middle Muschelkalk unit. In the present study areas, the two first marine floodin...

The Permian-Triassic rifting represents the first of the two Mesozoic rifting stages recorded in the Iberian Peninsula. Its first phases of development started during the Early Permian, and were linked to the beginning of the break-up of Pangea, the large, unique and rheologically unstable supercontinent that mainly resulted from the collision of G...
Article
The Guadalquivir Accretionary Complex forms a largely oblique prism at the northern edge of the Betic-Rif orogen, where Miocene sediments plus allochthonous evaporite-bearing units were accreted during the displacement of the Alborán Domain toward the west. Traditional interpretations end the tectonic structuring of the Betic Cordillera at the pres...
Article
This paper deals with the Middle Triassic-to-earliest Jurassic evaporite sedimentation in the epicontinental, eastern Iberian platform. This deposition occurred under extensional regime during the westwards migration of the Neotethys Ocean at the start of the Pangea break-up. Although attention is focused on the evaporitic episodes recorded in the...

Sulfate isotope compositions (δ34S and δ18O) and strontium isotope ratios (87Sr/86Sr) of Triassic evaporites in the Betic Cordillera are addressed for the first time in the present work. Isotope values have been determined in gypsum and anhydrite samples of the Germanic-type facies (Buntsandstein, Muschelkalk and Keuper) coming from different outcr...
Article
The study of the Late Triassic Zamoranos Formation and the comparison to coeval carbonate units provides new insights into the evolution and palaeogeography of carbonate platforms during major rifting phases in the Earth's history. The platform carbonates of the Zamoranos Formation record the last major transgression during the Triassic, and docume...
Article
This study focuses on storm deposits in the Muschelkalk facies of the Betic Cordillera (southern Spain) and interprets their deposition mechanisms. Three types of storm deposit are distinguished: (i) pot/gutter casts; (ii) tempestite beds; and (iii) storm‐winnowed deposits. Each deposit provides information about the carbonate platform environment...
Article
The Triassic sediments of the External Zones of the Betic Cordillera were deposited on the Southern Iberian Continental Palaeomargin. Two coeval Ladinian formations, namely the Siles Formation and the Cehegín Formation, are described to illustrate the facies and lithostratigraphic variability in the Muschelkalk carbonates. There has been some dispu...
Article
This paper reviews and discusses the different facies and nomenclature of the Triassic in the Betic Cordillera (S Spain). Emphasis is placed on problems encountered when studying Betic basin facies and palaeogeographic domains. In Triassic times, the Betic basin was positioned between the Iberian and Mesomediterranean Plates. We therefore propose t...
Article
This study integrates ichnological and sedimentological data in order to refine sequence stratigraphy and interpretations of sea-level dynamics for the Ladinian (Middle Triassic), Muschelkalk succession (Siles Formation) in the Betic Cordillera (southern Spain).Facies analysis was integrated with a detailed ichnological study, focused on the middle...

Estructura y paleogeografía de los materiales del Triásico en la terminación meridional del Arco de Cazorla (Jaén, Cordillera Bética): Implicaciones tectónicas. Structure and palaeogeography of Triassic materials at the southern end of the Cazorla Arc (Jaén, Cordillera Bética): Tectonic implications. ABSTRACT This study proposes a tectonic reinterp...
Article
The Betic Cordillera comprises the mountain range in the southern Iberian Peninsula that extends from Cadiz to Alicante, which displays typical features of alpine cordilleras. The Betic Cordillera includes two large geological tectonic domains, namely an External Zone, and an Internal Zone. The External Zone is essentially composed of epicontinenta...

The Cabo Cope Unit, which outcrops east of Aguilas (Murcia), belongs to the Maláguide tectonic Complex (Betic Internal Zone) and displays stratigraphic characteristics of particular interest, including Triassic bioclastic carbonate beds which are not common in the Maláguide units. Biostratigrafic fossils have been found in these beds and may correl...
Article
Pot casts and gutter casts are described for the first time in the lower part of the Majanillos Formation, a Middle Triassic carbonate unit located in the External Zones of the Betic Cordillera (southern Spain). Their identification, as well as their relation to tempestites, enables the better interpretation of the depositional environments and the...
Article
In southern Spain, within the Chiclana de Segura Formation of red detrital fades, enigmatic structures were found whose origins are discussed here. Each structure is composed of the union of elongated traces, two laterals and a shorter central one. All are concave epireliefs at the top of a sandstone bed whose age is assumed to be Ladinian (Triassi...
Article
The presence of Muschelkalk facies limestones, outcropping in the Triassic carbonate series of the Alpujarride units in the region of Murcia, has palaeogeographic consequences that are analysed. These very shallow marine Muschelkalk facies present calcareous fossiliferous levels and sedimentary facies analogous to those described in the External Be...
Article
The deposits of the Upper Triassic of the Subbetic Zone (Betic Cordillera) offer an example of semi-arid fluvial deposits passing into shallow-water facies through a mud-flat environment. From the study of the vertical changes in facies, a sequence model is proposed for the Upper Triassic succession, relating, for each systems tract, the changes in...

The lower Keuper of the central sector of Betic Cordillera shows a predominance of clays with variegated colours. They have intercalations of thin layers of sandstones (fine grain), gypsum and carbonates. Through sedimentological and stratigraphic analysis we can conclude that these materials are from a systems tract fluviocoastal further more it a...
