Evolution of the sources of Moroccan volcanism during the Neogene

New major and trace element analyses, Sr-Nd isotopic data and K-40-Ar-40 ages on Neogene and Quaternary lavas from Morocco lead to the conclusion that the observed temporal changes from calc-alkaline to transitional and finally alkaline magmatic activity reflect the contributions of distinct sources. According to our model, magmas originally derived from the melting of an European/Western Mediterranean-type asthenospheric mantle source interact during their ascent with either a subcontinental Ronda - Beni Bousera-/type lithospheric mantle (alkaline magmas) or a lithospheric mantle containing a crustal component, and the overlying continental crust (calc-alkaline and, to a lesser extent, transitional magmas).

New structural and petrologic data on Mesozoic schists in the Rhodope (Bulgaria): geodynamic implications

Structural analysis of low-grade rocks highlights the allochthonous character of Mesozoic schists in southeastern Rhodope, Bulgaria. The deformation can be related to the Late Jurassic-Early Cretaceous thrusting and Tertiary detachment faulting. Petrologic and geochemical data show a volcanic arc origin of the greenschists and basaltic rocks. These results are interpreted as representing an island arc-accretionary complex related to the southward subduction of the Meliata-Maliac Ocean under the supra-subduction back-arc Vardar ocean/island arc system. This arc-trench system collided with the Rhodope in Late Jurassic times. (C) 2003 Academie des sciences. Published by Editions scientifiques et medicales Elsevier SAS. All rights reserved.

Social perceptions of floods and flood management in a Mediterranean area (Costa Brava, Spain)

Taking as an example three study cases in the Costa Brava area, this paper examines the social perceptionof floods through surveys, interviews and Focus Group sessions. Perception is then related to vulnerability, flood management, and citizen’s preferences regarding alternatives to curb flood losses in the future. The study concludes that flood awareness and the willingness to take actions regarding this hazard are clearly related to the degree of social involvement with the affairs of the local community. Furthermore, participatory settings such as Focus Group sessions appear to enable a better environment for assessing and implementing flood management options that attempt to modify human activities rather than modify natural processes as has been frequently the case in the past

Permo-Triassic stratigraphy of the pelagonian zone in central Evia island (Greece)

A new subdivision of the pre-Jurassic Pelagonian Units in central Evia island is proposed these units are represented by syn- and post rift sequences, separated by a volcano-sedimentary episode. The syn-rift sequences comprise Permian siliciclastic sediments in Verrucano tectofacies, (Ano Mavropoulon Formation) and a small carbonate platform (Zigos Limestones) developed from the Permian to the Middle Anisian. The Ano Mavropoulon Fro, is subdivided into three members: the lower member (Permian s.l.) lying on the basement and characterised by medium-coarse elastic terrigenous sedimentation the middle member (Late Permian) Koprises limestones, made up of shallow-water limestones; the upper member (Latest Permian-Early Triassic) comprising elastic terrigenous and minor reworked carbonate sediments. A regional unconformity (earliest Triassic) separates the Zigos Lm. from the top of the Ano Mavropoulon Fm. The peritidal carbonates belonging to the Zigos Lm, have been subdivided into three lithofacies ranging in age from Spathian to Pelsonian (late Early Triassic to Middle Anisian). The volcanic episode is well constrained in all the Pelagonian domain. In central Evia, it has been dated from Middle Anisian to Early Carnian. The sub-alkaline to alkaline basalts comprised in the volcano-sedimentary sequence (Volcano-sedimentary Complex) have a within-plate affinity. The volcanism occurs between the syn-rift and post-rift stages, and it is probably not linked to the passive margin evolution proper. The post-rift sequences are represented by the onset of the Pelagonian platform aggradation (''Pantokrator'' Carnian to Middle-Late? Jurassic) The northern passive margin sequence of Pelagonia (palaeogeographic sense) is interpreted as related to the Maliak ocean opening during the Early Mesozoic.

Family Kungalariidae, n. fam., new Mesozoic entactinarian Radiolaria with a nassellarian-type initial spicule

Based on internal structure, a new family of entactinarian radiolarians, the Kungalariidae, is described with three new genera and four species: Kungalaria newcombi, Cachecreekaria californiensis, Transylvanaria devaensis, and T. hattorii. Members of this family have an eccentric internal, nassellarian-type initial spicule with bar MB, rays A, V, L, I, and spine Ax; a medullary shell built above the plane of lateral rays as in the cephalis of many nassellarians; and a spherical to subspherical cortical shell around the medullary shell. This new family is part of a group of Triassic entactinarians structurally intermediate between Entactinaria, or spicule-bearing Spumellaria, and Nassellaria. The new genera and species described occur in the Rhaetian of Queen Charlotte Islands, British Columbia, Aalenian to early-mid Bajocian of central Japan, Cenomanian of California, and Coniacian of Romania.

Alpine tectonic evolution of a Jurassic subduction-accretionary complex: Deformation, kinematics and 40Ar/39Ar age constraints on the Mesozoic low-grade schists of the Circum-Rhodope Belt in the eastern Rhodope-Thrace region, Bulgaria-Greece

Deformation of the Circum-Rhodope Belt Mesozoic (Middle Triassic to earliest Lower Cretaceous) low-grade schists underneath an arc-related ophiolitic magmatic suite and associated sedimentary successions in the eastern Rhodope-Thrace region occurred as a two-episode tectonic process: (i) Late Jurassic deformation of arc to margin units resulting from the eastern Rhodope-Evros arc-Rhodope terrane continental margin collision and accretion to that margin, and (ii) Middle Eocene deformation related to the Tertiary crustal extension and final collision resulting in the closure of the Vardar ocean south of the Rhodope terrane. The first deformational event D-1 is expressed by Late Jurassic NW-N vergent fold generations and the main and subsidiary planar-linear structures. Although overprinting, these structural elements depict uniform bulk north-directed thrust kinematics and are geometrically compatible with the increments of progressive deformation that develops in same greenschist-facies metamorphic grade. It followed the Early-Middle Jurassic magmatic evolution of the eastern Rhodope-Evros arc established on the upper plate of the southward subducting Maliac-Meliata oceanic lithosphere that established the Vardar Ocean in a supra-subduction back-arc setting. This first event resulted in the thrust-related tectonic emplacement of the Mesozoic schists in a supra-crustal level onto the Rhodope continental margin. This Late Jurassic-Early Cretaceous tectonic event related to N-vergent Balkan orogeny is well-constrained by geochronological data and traced at a regional-scale within distinct units of the Carpatho-Balkan Belt. Following subduction reversal towards the north whereby the Vardar Ocean was subducted beneath the Rhodope margin by latest Cretaceous times, the low-grade schists aquired a new position in the upper plate, and hence, the Mesozoic schists are lacking the Cretaceous S-directed tectono-metamorphic episode whose effects are widespread in the underlying high-grade basement. The subduction of the remnant Vardar Ocean located behind the colliding arc since the middle Cretaceous was responsible for its ultimate closure, Early Tertiary collision with the Pelagonian block and extension in the region caused the extensional collapse related to the second deformational event D-2. This extensional episode was experienced passively by the Mesozoic schists located in the hanging wall of the extensional detachments in Eocene times. It resulted in NE-SW oriented open folds representing corrugation antiforms of the extensional detachment surfaces, brittle faulting and burial history beneath thick Eocene sediments as indicated by 42.1-39.7 Ma Ar-40/Ar-39 mica plateau ages obtained in the study. The results provide structural constraints for the involvement components of Jurassic paleo-subduction zone in a Late Jurassic arc-continental margin collisional history that contributed to accretion-related crustal growth of the Rhodope terrane.
