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.

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.

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.
