Multichannel seismic reflection images across the transition between east Alborán and Algero‐Balearic basins show how crustal thickness decreases from about 5 s two‐way traveltime (TWTT, ∼15 km thick) in west (east basin) to ∼2 TWTT typical of oceanic crust (∼6 (Algero‐Balearic basin). We have differentiated three different domains this transition, mainly on basis signature. Boundaries are transitional lack evidence for major faults. Tilted blocks related extension very scarce all sampled...
Hypsometry is thought to be sensitive tectonic uplift rates and lithology differences. In this study we calculated hypsometric integrals (HIs) using as topographic sources two digital elevation models of 10 90 m pixel resolution in the Granada basin (SE Spain). The HI spatial distributions do not show clear patterns correlate with parameters mean or relief amplitude. However, when exploratory data analysis applied through local indices autocorrelation, hot spots are visible that improve...
Abstract The combination of metamorphic petrology tools and in situ laser 40 Ar/ 39 Ar dating on phengite (linking time growth, compositions P–T conditions) enables us to identify a detailed P–T–d–t path for the still debated tectonometamorphic evolution Nevado‐Filabride complex infer new geodynamic‐scale constraints. Our data show an isothermal decompression (at 550 °C) from 20 kbar Bédar‐Macael unit 14 Calar Alto down c. 3–4 both units at 2.8 mm year −1 . At 22–18 Ma, this first part...

Abstract What process triggered the Mediterranean Sea restriction remains debated since discovery of Messinian Salinity Crisis (MSC). Recent hypotheses infer that MSC initiated after closure Atlantic-Mediterranean Betic and Rifean corridors, being modulated through at Gibraltar Strait. These however, do not integrate contemporaneous speciation patterns faunal exchange between Iberia Africa several geological features like evaporite distribution. Exchange terrestrial biota occurred before,...
The Ronda peridotite supplies one of the best objects to document subcontinental mantle deformation, but its internal deformation and exhumation mechanisms remain controversial. Here we provide new structural data numerical results that constrain Oligocene‐Miocene history massif. We first describe a shear zone in northern massif developed subcrustal strain localization during decompression related partial melting. regime this evolved from penetrative NE‐SW stretching sinistral highlighted by...
To constrain the latest evolutionary stages and mechanisms of exhumation emplacement subcontinental peridotites in westernmost Mediterranean, we present here a detailed structural study transition from granular spinel peridotite to plagioclase tectonite western Ronda Peridotite (Betic Cordillera, southern Spain). We show that foliation represents an axial surface particularly well developed reverse limb downward facing moderately plunging inclined synform at base massif. The fold limbs are...
Abstract Two orthogonal extensional systems produced the collapse of Tell and Atlas thrust belts in northern Tunisia during Late Miocene to Pliocene a context NW‐SE plate convergence between Africa Eurasia. The older system shows several low‐angle normal faults (LANFs) associated high‐angle with ENE‐directed transport that half‐grabens hanging‐wall syncline basins late Tortonian Messinian. direction extension swinged towards SE Messinian, cutting into, tilting previous detachments. Extension...
Thermobarometry using mica‐chlorite local equilibria and structural analysis of three tectonic units the Alpujarride complex in southeastern Betics indicate that rocks underwent low‐pressure/low‐temperature metamorphism are found below higher‐grade blueschist facies rocks. Moreover, high‐pressure/low‐temperature (HP/LT) contrasting (P‐T) evolutions. The structurally highest unit was exhumed a typical postorogenic high‐temperature geothermal context andalusite stability field, while...
Extremely tight arcs, framed within the Eurasia-Africa convergence region, developed during Neogene on both sides of western Mediterranean. A complex interplate deformation zone has been invoked to explain their structural trend-line patterns, shortening directions and development back-arc basins. Updated kinematic maps, combined with earthquake data covering complete hinge Gibraltar arc help us explore mode strain partitioning from 25My ago present. During Miocene, pattern showed...
Quaternary activity of folds and faults can be assessed by the analysis drainage network evaluation geomorphic indexes. These analyses are especially productive in semiarid areas where tectonic rates low-to-moderate dating is limited. In this work, we have revisited most relevant GIS-based methodologies used to assess using morphometric discuss implications two key central eastern Betic Cordillera (Sierra Nevada Sierra Alhamilla regions). area, use indexes mountain range neighboring Granada...
Abstract Interpretation of new multichannel seismic reflection profiles indicates that the Palomares margin was formed by crustal-scale extension and coeval magmatic accretion during middle to late Miocene opening Algero-Balearic basin. The at transition between thinned continental crust intruded arc volcanism back-arc oceanic crust. Deformation produced later positive inversion offshore onshore is partitioned ~N50°E striking reverse faults associated folds like Sierra Cabrera Abubacer...
Abstract The current diffuse-strain model of the collision between Africa and Eurasia in western Mediterranean predicts a broad region with deformation distributed among numerous faults moderate-magnitude seismicity. However, is untested because most occurs underwater, at poorly characterized undetermined slip. Here we assess analysing two active offshore fault systems associated prominent seafloor relief region. We use pre-stack depth migrated seismic images to estimate, for first time,...
The existence of normal faults that moved at low angles (less than 20°) has long been debated. One possible low‐angle fault is the S detachment west Galicia (Spain) margin and thought to occur top serpentinized mantle. It unlikely was a large submarine slide as it probably active over several million years without development any compressional features such toe thrusts, appears have rooted beneath conjugate Flemish Cap margin, similar structures elsewhere also appear be detachments. Here we...
