GEOLOGIA ROMANIEI PDF
Institutul Geologic al României reprezintă una dintre cele mai vechi instituţii centrale create de statul român modern. Toate foile hărţilor geologice şi hidrogeologice ale României editate până în prezent sunt stocate Muzeul de Geologie. V. MUTIHAC Iuliana Maria STRATULAT Roxana Magdalena FECHET GEOLOGIA ROMÂNIEI BUCUREŞTI 1 ÎNCADRAREA. Din anul când a avut loc Congresul Internațional de Geologie din Bologna s-a hotărât Harta este editată de către Institutul Geologic al României.

Rom J Tecton Reg Geol. Late Cretaceous exhumation of the Bihor Unit Time—temperature paths, fission-track modelling Kounov and Schmidand the deposition of syn- to post-tectonic sediments on all but the lowest tectonic units in the nappe stack allow constraining general uplift of the study area during Late Cretaceous times Fig.
The thin section shows a mylonitic fabric and ductile NE-directed shearing of quartz bands. Phyllonites and metagranites are the dominant lithologies, but amphibolites and lenses of calcitic and dolomitic marbles, often associated with quartzites, characterize the retrogressed portions of pre-Mesozoic basement.
Biotite ages were calculated using the Rb-decay constant of 1.
Abbreviations of mineral names are according to Whitney and Evans a Discordant age spectrum. Legaturi paleobiogeografice ale faunei de vertebrate continentale Maastrichtian superioare din Bazinul Hateg. Furthermore, concordant Ar—Ar hornblende ca. The thin section shows an anastomising muscovite foliation romanisi around zoned garnet minerals up to 1.
Intense folding during the subsequent D2 phase is responsible for varying strike-slip bnormal fault cand thrust geometries d of the D1-phase. In general, the Rb—Sr biotite data set yields younger ages than corresponding Ar—Ar muscovite ages Fig. Polyphase overprinting of pre-Alpine basement units and a significant thermal overprint during the Alpine evolution led to a complex structure with strong lateral and vertical gradients.
Neagu, Th, Dragastan, O. Rom J Petrol This phase of shortening is geodynamically linked to gellogia N- to NE-directed subduction of the Neotethys Vardar ocean beneath Europe-derived units romanoei.

Time—temperature paths from the structurally highest basement nappe of the Apuseni Mountains in combination with sedimentary data indicate exhumation and a position close to the surface after the Late Jurassic emplacement of the South Apuseni Ophiolites. Insula dinosaurilor – Noi interpretari ale vertebratelor cretacice din Bazinul Hateg dupa ani de la descoperire Csiki, Z.
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.
Tectonic implications of paleomagnetic research into Upper Cretaceous magmatic rocks in the Apuseni Mountains, Romania. Latest Cretaceous deformation Our kinematic observations show top-W-directed deformation under brittle conditions Fig. Late Cretaceous intra-oceanic magmatism in the internal Dinarides northern Bosnia and Herzegovina: Mineral exploration and sustainable development, pp — Nicolae I, Saccani E. Time—temperature paths of the Bihor Unit show cooling from medium- to low-grade thermal conditions at the transition between Early and Late Cretaceous Fig.
Geeologia biotite ages calculated with feldspar sample MR11 or whole-rock isotope composition all other samples. Shear bands in the Biharia Nappe s. Kinematic data from the Bihor Unit in the northern part of the study area sector C in Figs. However, due to the lack of index minerals, no constraint for thermal peak conditions in the Biharia Nappe s. Earth Planet Sci Lett. Eastern European Alpine system and the Carpathian orocline as an example of collision tectonics.
Numar Special The Transylvanian Basin Romania and its relation to the Carpathian fold and thrust belt: Differences in timing of cooling between the tectonic units relate to their structural position in the nappe stack.
Balen D Microstructural, geothermobarometric and geochronological constraints on the complex Alpine collisional history recorded on the romamiei Psunj Complex metamorphic rocks of the Slavonian Mts.
Polonica, 48, 4, Late Cretaceous extension led to the formation of half-grabens and associated hanging-wall deposition of rimaniei to post-tectonic sediments in the Apuseni Mountains and the South Carpathians e.
Symposia Organizing Comittee member 1. Lithostratigraphic correlation of Precambrian in the Romanian Carpathians. New Ar—Ar muscovite and Rb—Sr biotite age data in combination with structural analyses from the Apuseni Mountains provide feologia constraints on the timing and kinematics of deformation during the Cretaceous.
Peer reviewed, ISI periodicals 1. Provinciality of the Mediterranean Lower Jurassic brachiopod fauna: 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 Chem Geol Isot Geosci Sect.
This exhumation takes place along low-angle detachments and exposes structurally lower parts of the basement units.
