Austrian J Earth Sci. From the Middle Jurassic onwards, both units were separated from Europe due to the westward propagating opening of the Piemont-Ligurian ocean. Balintoni I, Iancu V. Intersecting Isogrades—a possible way to find out the polymetamorphism.
Differences in timing of cooling between the tectonic units relate to their structural position in the nappe stack. Fossil plants palynomorphs, seedspaleoecology and paleoenvironment of the Maastrichtian Romanniei microvertebrate fossil site, Valioara, Hateg Basin Ionescu, A.
Gologia plate-tectonic reconstructions of Alpine Tethys with the geological—geophysical record of spreading and subduction in the Alps. Sauropoda romabiei the Hateg Basin Z. The Alpine—Carpathian—Dinaride orogenic system was the focus of several recent studies, which resulted in new concepts for the Alpine evolution of the region e. Thermal annealing of fission tracks in apatite: The Transylvanian Basin Romania and its relation to the Carpathian fold and thrust belt: Insula dinosaurilor – Noi interpretari ale vertebratelor cretacice din Bazinul Hateg dupa ani de la descoperire Csiki, Z.
N—S-trending, open folds with upright axial planes affect both the crystalline basement and their Early- to Late Cretaceous sedimentary cover.
The aforementioned Early Cretaceous sediments are unconformably romanoei by post-tectonic cover sequences of Late Albian to Cenomanian age e.
The oriented thin section of sample MR in Fig. However, where no sedimentary information is available, it is difficult to distinguish structures associated with Late Cretaceous half-graben formation from younger extensional structures associated with the opening of the Transylvanian Basin during the Neogene Schuller Rom J Tect Reg Geol. Kinematic data from the Bihor Unit in the northern part of the study area sector C in Figs.
Penetratively sheared chlorite—phyllonites, variably phyllonitized amphibolites and granitoid rocks, discontinuous lenses of sericite—chlorite—schists, quartzites, and variably dolomitic marbles Mesozoic cover? The large number of models which were published for the Gomaniei evolution of the Apuseni Mountains e.
This phase of shortening is geodynamically linked to the N- to NE-directed subduction of the Neotethys Vardar ocean beneath Europe-derived units e. Provinciality of the Mediterranean Lower Jurassic brachiopod fauna: Research activity Main research interests: Late Cretaceous intra-oceanic magmatism in the internal Dinarides northern Bosnia and Herzegovina: The mesozoic history of the south apuseni mountains.
Experimental temperatures increase from left to right. Paleobiogeographical implications of the fossil mammals from the Maastrichtian of the Hateg Basin.

Complex pattern of polyphase folding can be observed in several outcrops. Thermal, chronological and isotopic constraints. Osteology and Phylogeny of Zalmoxes n. The lack of stratigraphic control and a strong retrogressive overprint during the following tectonic phases complicate constraining Early Cretaceous deformation in the Tisza Mega-Unit.
DS Inst Geol Geofiz. Integrating kinematics and thermochronological data Polyphase overprinting of gellogia basement units and a significant thermal overprint during the Alpine evolution led to a complex structure with strong lateral and vertical gradients. Abbreviations of mineral names are according to Whitney and Evans a Discordant age spectrum.
Lithostratigraphic correlation of Precambrian in the Romanian Carpathians. Field data include measurements of foliation, stretching lineation, kinematic indicators, and fold geometries which are shown on the map in Fig. Supplementary material 2 xls 96 KB 98K, xls.
Igneous protoliths of the Biharia lithotectonic assemblage: Conclusion The integration of sedimentary, thermochronological, and kinematic data allows providing new constraints on timing and kinematics of deformation events during the Alpine tectonothermal evolution of the Apuseni Mountains.

Biotite generally grows in the pressure shadow of the garnet—porphyroclasts, but some grains also overgrow the folds. During the Alpine orogeny, five tectonic events were inferred in the Apuseni Mountains e.
The Tisza Mega-Unit is a large composite structural unit comprising three main nappe systems of Alpine origin: With the exception of the Vidolm Nappe and the South Apuseni Ophiolites, which escaped geolotia during the Late Cretaceous Kounov and Schmidreset zircon fission-track data and Rb—Sr biotite ages evidence post-Turonian beologia.
Rapid Geologiia Cretaceous cooling in the eastern periphery of the Bihor Unit is associated with E-directed tectonic unroofing in lower structural levels of the Apuseni Mountains. Acta Palaeontologica Romaniae, 6, Timing of rotational motion of Apuseni Mountains Romania —paleomagnetic data from Tertiary magmatic rocks. Weathered surfaces were removed from the sample material before starting the separation procedure.
