The provenance of a turbidite system within a tectonically active wrench basin: Insights from heavy mineral characteristics of Miocene sandstones in the Tabernas Basin, south‐east Spain

open access: yesThe Depositional Record
This paper provides insight into the provenance of the Late Miocene turbidite succession of the Tabernas Basin. Although this area has been extensively studied, only limited attention has been paid to sediment provenance.

A possible 5 km wide impact structure with associated 22 km wide exterior collapse terrain in the Alhabia–Tabernas Basin, southeastern Spain

open access: yesMeteoritics &Planetary Science, Volume 58, Issue 10, Page 1512-1539, October 2023., 2023
Abstract The Tabernas–Alhabia Basin is a structural depression situated in the province of Almería, southeastern Spain. The basin is filled with Neogene, Pliocene, and Pleistocene sediments resting discordantly on a Paleozoic metamorphic basement. During the marine Tortonian sedimentation, a bed of breccia (Gordo megabed) was formed.

Metamorphic Domes in Northern Tunisia: Exhuming the Roots of Nappe Belts by Widespread Post‐Subduction Delamination in the Western Mediterranean

open access: yesTectonics, Volume 42, Issue 6, June 2023., 2023
Abstract Cenozoic extension in the Western Mediterranean has been related to the dynamics of back‐arc domains. Although, in most of its orogenic belts extension propagated into the fore‐arc nappe domains. Here we revisit the structure, metamorphism and radiometric ages of the Tunisian Tell, where HP/LT rocks (350°C at 0.8 GPa), were exhumed by the ...

Pre‐Subduction Architecture Controls Coherent Underplating During Subduction and Exhumation (Nevado‐Filábride Complex, Southern Spain)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 24, Issue 3, March 2023., 2023
Abstract The interplay between structural and metamorphic processes operating along the deep plate interface in subduction zones remains elusive as much of the geologic record is recycled into the mantle. In some cases, metamorphosed subducted rocks are underplated and exhumed to the surface, providing critical constraints on structural processes and ...

Monitoring sedimentary areas from mine waste products with Sentinel‐2 satellite images: A case study in the SE of Spain

open access: yesEuropean Journal of Soil Science, Volume 74, Issue 1, January–February 2023., 2023
Abstract Torrential rainfall regimes, among others, are the origin of accelerated soil erosion. The Spanish southeastern Mediterranean region is characterised by an arid climate regime affected by extreme erosion episodes with an important loss of sediments.

Seismic Observation and Location of a Meteor Burst From a Dense Station Deployment in Southern Spain

open access: yesGeophysical Research Letters, Volume 49, Issue 24, 28 December 2022., 2022
Abstract A meteor event on 11 December 2016 in southern Spain was accompanied by an audible boom and felt vibrations. Acousto‐seismic coupling of the near‐field pressure wave has been recorded by an unusually large number of 44 local seismic stations.

Refined Tectonic Evolution of the Betic‐Rif Orogen Through Integrated 3‐D Microstructural Analysis and Sm‐Nd Dating of Garnet Porphyroblasts

open access: yesTectonics, Volume 41, Issue 10, October 2022., 2022
Abstract High‐resolution microstructural analysis of porphyroblast inclusion trails integrated with Sm‐Nd garnet geochronology has provided new insight into the tectonic history of the Betic‐Rif orogen. Three principal age groups of porphyroblasts are demonstrated with distinctly oriented inclusion‐trails.

Relief and climate influence on isotopic composition of Atlantic‐Mediterranean karst spring waters (Andalusia, southern Spain)

open access: yesHydrological Processes, Volume 36, Issue 9, September 2022., 2022
Isotopic analysis of groundwater from Andalusian karst springs for 2H, 18O and deuterium excess showed differences between diffuse groundwater and meteoric waters isotopic composition. These differences are due to effects controlled by the great heterogeneity in the climate and relief in this territory.

The Role of Faults as Barriers in Confined Seismic Sequences: 2021 Seismicity in the Granada Basin (Betic Cordillera)

open access: yesTectonics, Volume 41, Issue 9, September 2022., 2022
Abstract Fault barriers are key structures for studying seismic hazard in regions of intense brittle deformation. The interaction between fault sets affects their seismogenic behavior, if some of them act as barriers. The Granada Basin, in the Betic Cordillera, is a region affected by shallow brittle deformation, as it was the scenario for the recent ...

Tectonic Evolution of the Nevado‐Filábride Complex (Sierra de Los Filábres, Southeastern Spain): Insights From New Structural and Geochronological Data

open access: yesTectonics, Volume 41, Issue 8, August 2022., 2022
Abstract The high‐pressure metamorphic Nevado‐Filábride Complex (NFC) in the Betics mountain range of southeastern Spain exhibits continental and ocean‐derived tectonic units, which are key for understanding the geodynamic evolution of the Western Mediterranean.
