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.

Remnants of a Triassic ocean.
Teeth of multituberculate mammals from the Late Cretaceous of Romania. Tectonic, magmatic, and metallogenic evolution of the Late Cretaceous arc in the Carpathian—Balkan orogen.
The oldest age for the Vidolm Nappe comes from sample MR11 geilogia plateau age: Due to Late Cretaceous overprinting under sub-greenschist to greenschist-facies conditions, structures related to the Early Cretaceous deformation are still poorly constrained in the eastern Apuseni Mountains. Alpine crustal shear zones and pre-alpine basement terranes in the Romanian Carpathians and Apuseni Mountains.
Sample MR yields a discordant age spectrum. Calculation of ages was done using Isoplot software Version 4.
Where the samples were suitable, biotite and muscovite concentrates were prepared from the same sample. Tectonic implications of paleomagnetic research into Upper Romanii magmatic rocks in the Apuseni Mountains, Romania. Geological Society of Geoloiga 5.
The “Dinosaur Island” — New interpretation of the Hateg vertebrate fauna after years. Geodynamic implications of Jurassic ophiolites associated with island-arc volcanics, South Apuseni Mountains, western Romania.
Kinematic data from the Bihor Unit in the northern part of the study area sector C in Figs.
Geological background The Apuseni Mountains mainly comprise pre-Variscan, polyphase metamorphic crystalline basement, Palaeozoic granitoid intrusions, Upper Palaeozoic cover, Jurassic ophiolites, and Mesozoic sequences of variable thickness e. A new giant pterosaur with a robust skull from the latest Cretaceous of Romania. Lithostratigraphic correlation of Precambrian in the Romanian Carpathians.
The direction of obduction, the palaeogeographic position of the Dacia Mega-Unit, and more specifically the attribution of the ophiolites to a northern Piemont-Liguria or southern Neotethys oceanic realm are still a matter of debate cf. Evaluation of the 87 87 Rb decay constant by age comparison against the U—Pb system.
During the Alpine orogeny, five tectonic events were inferred in the Apuseni Mountains e. Abbreviations of mineral names tomaniei according to Whitney and Evans In these parts, biotite and garnet are well preserved e. All four Ar—Ar muscovite age spectra show a staircase pattern Fig. Rom J Petrol Austrian J Earth Sci. Equal-area, lower-hemisphere stereographic plots of stretching lineation and contoured pi-plots of main foliation, separated according to romahiei sectors given in Figs.
Investigations of an intrusive contact, northwest Nelson, New ZealandI. Slow cooling of the Vidolm Nappe and the coeval cessation of deposition of platform carbonates on top of the ophiolites shallowing upward cycles; cf.
The thin section shows a mylonitic fabric and ductile NE-directed shearing of quartz bands.
The Tisza Megatectonic Unit in the light of palaeomagnetic data. Personal data – Name: Alpine regional metamorphism in the main tectonic units of Hungary: Sauropoda from the Hateg Basin. Diagrams are arranged relative to the structural position of the tectonic units: Mesozoic evolution rlmaniei the Tisza Mega-unit.
Sample localities are indicated in Fig.

Kinematic indicators and stretching lineation yield evidence for NW-directed thrusting and nappe stacking not only in the Dacia Mega-Unit of the southern and eastern Apuseni Mts. The Alpine-Carpathian-Dinaridic orogenic system: 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. The Apuseni Mountains in Romania take a central position within this system and expose the contact between the Tisza and Dacia Mega-Units together with obducted ophiolites derived from the Neotethys oceanwhich is otherwise largely covered by Cenozoic sediments of the Pannonian and Transylvanian basins Fig.
