Tectonic implications of paleomagnetic research into Upper Cretaceous magmatic rocks in the Apuseni Mountains, Romania. Shear bands from structurally higher parts i.
Structure of the Apuseni Mts. New and previously published rmoaniei sets are integrated into time—temperature paths Fig. Strata, 1, 11, Legend is given in Fig. Romanian Society of Palaeontologists; 4. Thus, we interpret this D1 deformation phase in the study area as an interference between the neighbouring position of the Tisza and Dacia Mega-Units cf.
Geology of hungary, paleozoic ii. Thus, in the following section, we correlate sedimentary, structural, and thermochronological data to constrain the Alpine tectonothermal evolution of the tectonic units in the study area Fig.
A grey arrow illustrates the cooling path of the tectonic units based on thermal modelling of apatite fission-track data Kounov and Schmid European Association of Vertebrate Paleontologists; 3.

Lower—Middle Jurassic extensional tectonics. 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. Biographical information – This extension is associated with hanging-wall sedimentation of syn- to post-tectonic sediments f.
Legaturi paleobiogeografice ale faunei de vertebrate continentale Maastrichtian superioare din Bazinul Hateg. 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.
This age range is also shown in detrital zircons population 3: 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. Remnants of a Triassic ocean. The intense chloritization of biotites from the Biharia Nappe s.
In the Southern Apuseni Mts. Jurassic microplate movements and brachiopod migrations in the western part of the Tethys. 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. Fission track analysis and its applications to geological problems. Abbreviations of mineral names are in accordance with Whitney and Evans 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.

Intense ductile deformation is visible in the thin section Fig. Slow cooling of the Vidolm Nappe and the coeval cessation of romzniei of platform carbonates on top of the ophiolites shallowing upward cycles; cf. Sauropoda from the Hateg Basin Z.

Naturwissenschaften, 89, 5. Orientation of main foliation, stretching lineation, kinematic indicators, and fold axes is given on the map. Calculation of ages was done using Isoplot software Version 4. Introduction 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. Syn- to post-tectonic flysch-like sediments which unconformably overlie the tectonic units of the Biharia Nappe System provide additional constraints on this Early Cretaceous deformation e.
