Gypsum karst in the Betic Cordillera (south Spain)

Carbonates and Evaporites, 2002
Among the numerous karstified gypsum outcrops of the Betic Cordillera, in this article we present three extreme examples, with markedly different origins and development: (1) the Antequera gypsum karst, where diapiric phenomena have had a decisive influence on the geomorphological and hydrogeological evolution of the area; (2) the karst in gypsum of ...

Denudation rates and tectonic geomorphology of the Spanish Betic Cordillera

Earth and Planetary Science Letters, 2014
Abstract The tectonic control on landscape morphology and long-term denudation is largely documented for settings with high uplift rates. Relatively little is known about the rates of geomorphic response in areas of low tectonic uplift. Here, we evaluate spatial variations in denudation of the Spanish Betic Cordillera based on cosmogenic 10Be-derived

Palaeomagnetic rotations in the eastern Betic Cordillera, southern Spain

Earth and Planetary Science Letters, 1993
Palaeomagnetic declinations from the External Zones of the eastern Betic Cordillera (southern Spain) and an adjacent area of the Internal Zone indicate variable and locally very large clockwise rotations. The rotations occurred after latest Oligocene times, and probably before the late Miocene.

Subsidence analyses from the Betic Cordillera, southeast Spain

Basin Research, 2003
ABSTRACTFifty‐four Mesozoic–Cenozoic stratigraphic sections from the Betic Cordillera of southeast Spain have been analysed in order to estimate the timing and amount of lithospheric stretching that occurred at the western end of the Tethyan Ocean since the Hercynian Orogeny.

Stress and palaeostress in the Betic-Rif cordilleras (Miocene to the present)

Tectonophysics, 1993
Palaeostress orientation in the Betic-Rif Cordilleras can be determined for the Miocene to the Quaternary by analysis of brittle microstructures (faults, joints, striated pebbles and stylolites). In the central and northern South Iberian Domain, σ1 was subhorizontal and trended NW-SE, from the Early Miocene to the present.

Recent Tectonic Structures in a Transect of the Central Betic Cordillera

Pure and Applied Geophysics, 2004
The Betic Cordillera has undergone recent Alpine deformations related to the Eurasian-African plate interaction boundary. Most of the present-day relief has been built up since Tortonian times, and is related to the development of folds and faults that are overprinted on older deformations, and some of the faults may be considered as out-of-sequence ...

Structure and palaeogeography of the External Betic Cordillera, southern Spain

Marine and Petroleum Geology, 1992
Abstract A structural interpretation of the External Betic Cordillera in the Granada-Jaen area of southern Spain is proposed based on the interpretation of seismic reflection profiles, subsurface well control and a balanced cross-section. Restoration of this balanced cross-section results in a new palaeogeographical interpretation for the area and a ...

On the tectonics of the eastern Betic Cordilleras (SE Spain)

Geologische Rundschau, 1964
The tectonically deepest part of the eastern Betic Cordilleras consists of rocks showing medium grade metamorphism of alpine age. In this zone several individual tectonic units are distinguished, each with a basis of polymetamorphic pre-Silurian schists, covered by a sequence of younger metamorphites considered to be partly of Triassic age.

The Guadalentín Tectonic Depression, Betic Cordillera, Murcia

2014
The tectonic Guadalentin Depression is an elongated Quaternary sedimentary basin generated by a system of left-lateral strike-slip faults on the eastern Betic Cordillera. The Lorca-Alhama de Murcia fault (LAF) is the most relevant structure, controlling the 100-km-long western margin of the depression with a prominent mountain front.

Geologic evolution of the westernmost part of the internal Betic zone (Betic Cordilleras, Southern Spain)

Geologische Rundschau, 1980
The Serrania de Ronda (western Betic Cordilleras, S-Spain) is formed by different tectonic units of the Betic internal domain. Stratigraphic correlations of the “Permo-Triassic” and Triassic sedimentary sequences imply that one part of the Mesozoic carbonates of the Rondaides (Dorsale betique), namely the Cabrilla unit (Dorsale interne), is shearedoff ...
