Abstract Integration of structural, stratigraphic, and paleomagnetic data from the N–S trending structures Ainsa Oblique Zone reveals kinematics major thrust salient in central Pyrenees. These experienced clockwise vertical axis rotations that vary 70° east (Mediano anticline) to 55° west (Boltaña anticline). Clockwise 60° 45° occurred early Lutetian late Bartonian when folds thrusts developed. This rotation stage resulted a difference about 50 km amount displacement on Gavarnie an...
ABSTRACT This paper presents new magnetostratigraphic results from a 1100‐m‐thick composite section across the marine to continental sediments of central part SE margin Ebro basin (NE Spain). Integration with existing and biochronological data allows robust correlation geomagnetic polarity time scale. The resulting absolute chronology ranges 36.3 31.1 Ma (Priabonian Rupelian), yields an interpolated age ∼36.0 (within chron C16n.2n) for youngest eastern basin. is in concordance...
Abstract A well‐preserved 11.8‐million‐years‐old lower face attributed to the seminal taxon Dryopithecus fontani (Primates, Hominidae) from Catalan site ACM/C3‐Ae of Hostalets de Pierola area (Vallès‐Penedès Basin, Catalonia, NE Spain) is described. The new data indicate that D. distinct at genus level Late Miocene European taxa previously , which are here reassigned Hispanopithecus . facial specimen also suggests and Middle Pierolapithecus catalaunicus not synonymous.

ABSTRACT The timing of deformation in the northern Zagros Folded Belt is poorly constrained because lack an accurate absolute chronology syntectonic sedimentary sequences. foreland basin infill part Fars arc composed supratidal sabkha deposits (Razak Fm), medium‐grained deltaic (Agha Jari Fm) and coarse conglomerates nearshore fan delta at base (Bakhtyari Fm, Bk1) continental alluvial top section Bk2). A magnetostratigraphic study was carried out a composite spanning about 1300 m on flank...
The syntectonic continental conglomerates of the South-Central Pyrenees record late stages thin-skinned transport South-Pyrenean Central Units and onset exhumation Pyrenean Axial Zone (AZ) in core orogen. New magnetostratigraphic data these have established their age as Late Lutetian to Oligocene. reveal that materials were deposited during intense periods tectonic activity chain not cessation deformation considered previously. ages been combined with new detrital apatite fission track (AFT)...
The precise determination of the tectonic deformation timing such as thrust emplacement has always been a challenge for understanding evolution fold-and-thrust belts. In Catalan Coastal Ranges, this issue traditionally addressed through mapping and analysis syn-tectonic successions preserved in SE margin Ebro Basin. However, age Paleogene contractional structures located towards hinterland responsible inversion uplift inherited Mesozoic structure remained uncertain due to lack syn-kinematic...
The EOT (Eocene-Oligocene Transition) stands out among the greatest reorganizations of global climate during Cenozoic era, marking a shift from Late Eocene “greenhouse” state to “icehouse” conditions on Oligocene (34-33.5 Ma). While its temporal framework is well established and characteristics are increasingly understood, further research required assess regional imprints this major climatic shift. In regard, records epicontinental basins particularly...
The Eocene-Oligocene Transition (EOT) marks one of the most profound climatic shifts in Earth’s history, as recorded by deep-sea isotope data. This interval is characterized global cooling and onset modern icehouse conditions, making it a focal point paleoclimate research. Understanding expression EOT globally well its regional variability requires correlation disparate records over globe. To achieve this magnetostratigraphic data key to provide necessary independent age...
The monogenetic Quaternary La Garrotxa Volcanic Field is located in the North-East of Iberian Peninsula and was active from Middle Pleistocene to Early Holocene, thus, being youngest known volcanic activity Peninsula. It forms part Catalan Zone (Girona, NE Peninsula), one alkaline provinces European rift system.The main goal this work obtain a reliable full-vector record Earth’s Magnetic (EMF) recorded by 247 kya 16 lava-flows Field. With purpose, fifteen basaltic with absolute...
Over the last decades, there has been an increasing interest on chronology, distribution and mammal taxonomy (including hominins) related with faunal turnovers that took place around Pliocene-Pleistocene transition [ca. 1.8 mega-annum (Ma)] in Europe. However, these are not fully understood due to: precarious nature of period's fossil record; "non-coexistence" this record many species involved; enormous geographical area encompassed. This palaeontological information gap can now be part...
This study presents a combined biostratigraphic (calcareous nannofossils, larger foraminifers) and magnetostratigraphic of the Middle Late Eocene marine units Igualada area, eastern Ebro Basin. The studied sections Santa Maria de Miralles La Tossa encompass complete succession Group, where assemblages rich in foraminifers have been since early 1950's. A total 224 paleomagnetic sites 62 samples were collected along 1350m-thick section that ranges from chron C20n to C16n (~43Ma ~36Ma)....
Abstract The integration of biostratigraphy, strontium isotope stratigraphy, and magnetostratigraphy allowed for the precise dating >3.0-km-thick marine to non-marine foreland sedimentary succession within Dowlatabad growth syncline along Frontal Fars arc in Zagros Fold Belt that extends from eastern Turkey southern Iran. This area was missing link complete syntectonic deposits quantify migration belts as well propagation folding across entire Mesopotamian basin. Both are essential...
A R Y New full-vector archaeomagnetic data for North Africa recovered from the study of six kilns, five Tunisia and one Morocco, are presented.Archaeological historical considerations, along with three radiocarbon dates, indicate that age kilns ranges between 9th 15th centuries AD.Rock magnetic analyses showed principal carriers magnetite low Ti titanomagnetite, variable contributions thermally stable maghemite a high coercivity phase unblocking temperatures.The mineralogy studied material...
Abstract The propagation of the deformation front in foreland systems is typically accompanied by incorporation parts basin into wedge‐top piggy‐back basins, this process likely producing considerable changes to sedimentation rates (SR). Here we investigate spatial‐temporal evolution SR for Tremp–Jaca Basin Southern Pyrenees during its from a wedge‐top, foreredeep, forebulge configuration stage. were controlled series tectonic structures that influenced subsidence distribution and modified...
Abstract Unraveling the short‐term behavior of Earth's past geomagnetic field at regional scales is crucial for understanding its global and, thus, dynamics deep Earth. In this context, obtaining accurate full‐vector records from regions where archeomagnetic data are absent becomes essential. Here, we present first Central Asia, derived analysis nine archeological kilns sampled in South Uzbekistan, dating back to period between 200 BCE and 1429 CE. To obtain these new data, conducted thermal...
The timing of deformation and the age sediments in foreland basins are key information for reconstructing tectonic history orogenic belts. This study, utilized magnetostratigraphic techniques to determine ages ∼ 2.5 km-thick strata within Zagros folded basin flank NW-SE-trending Emam Hassan anticline, located above N–S-trending Khanaqin blind basement fault. fault separates Lurestan arc Iran from Kirkuk embayment Iraqi Kurdistan.
