The early evolution of SW Europe Variscides started by opening the Rheic ocean at ∼500 Ma, splitting Avalonia from Armorica/Iberia. Subduction on SE side generated Paleotethys back‐arc basin (430–390 Armorica Iberia), with development Porto‐Tomar‐Ferreira do Alentejo (PTFA) dextral transform defining boundary between continental and Finisterra microplate to W. Obduction was followed Armorica/Iberia collision emplacement NW Iberian Allochthonous Units 390–370 whereas toward west PTFA, there...
Abstract The transition from seamount to oceanic island typically involves surtseyan volcanism. However, the geological record at many islands in NE Atlantic—all located within slow‐moving Nubian plate—does not exhibit evidence for an emergent phase but rather erosive unconformity between submarine basement and overlying subaerial shield sequences. This suggests that may frequently occur by a relative fall of sea level through uplift, eustatic changes, or combination both, involve summit In...
The Variscan ophiolites in southern Iberia occur both as a thin belt along the boundary between Ossa-Morena (OMZ) and South Portuguese Zones (SPZ) (Beja-Acebuches ophiolite) dismembered, scattered allochthonous klippen on top of lower Palaeozoic sequences within internal areas OMZ. Beja-Acebuches ophiolite corresponds to amphibolite-serpentinite displaying lithological organisation including, from bottom top: metaperidotites (harzburgitic/dunitic) cumulate pyroxenites, flaser gabbros with...
Abstract The structure of the southernmost domain Ossa Morena Zone in Portugal (south sector Iberian Autochthonous Terrane) is strongly controlled by earlier deformation events. first two events correspond to tangential strain regimes, marked subhorizontal milonitic foliations. These seem be directly related with obduction/subduction process during Variscan ocean closure and emplacement Beja-Acebuches Oceanic Terrane. In this (Évora-Beja Domain), upper tectono-stratigraphic unit (Moura...
The Early Paleozoic geodynamic evolution in SW Iberia is believed to have been dominated by the opening of Rheic Ocean. Ocean generally accepted resulted from drift peri-Gondwanan terranes such as Avalonia northern margin Gondwana during Late CambrianEarly Ordovician times. closure was final result a continent-continent collision between and Laurussia that produced Variscan orogen. Ossa-Morena Zone peri-Gondwana terrane, which preserves spread fragments ophiolites - Internal Zones Ophiolite...
Forty‐one magnetotelluric soundings were carried out along a 200 km‐long profile (approximately NNE‐SSW) across the three major geotectonic units in SW Iberia. A model obtained from two‐dimensional inversion of data set reveals high conductivity zones middle‐lower crust (10–30 km). Two these correspond to transition between main units: one South Portuguese Zone and Ossa Morena Zone, interpreted as having been caused by metasediments, other Central Iberia associated with shear zone...
The focus area is located along Beja and Faro districts (southwestern of Portugal), where the Baixo Alentejo Flysch Group exists, composed Mértola, Mira, Brejeira Formations. aim this article to characterize groundwater contamination by toluene, one petroleum products that may originate from natural systems have been introduced into environment seepage. For study, twenty soil samples thirty-one water were collected, in 2016, artesian wells, boreholes, springs, analyzed a GC-FID system....
