N—S-trending, open folds with upright axial planes affect both the crystalline basement and their Early- to Late Cretaceous sedimentary cover. This indicates a possible internal thermal gradient for the Vidolm Nappe. D1 summarizes complex, NE-directed deformation as shown through stretching lineation and geoolgia inclined folds a. The timing of exhumation agrees with results from other parts of the Dacia Mega-Unit, e.

Intense folding during the subsequent D2 phase is responsible for varying strike-slip bnormal fault cand thrust geometries d of the D1-phase.

Nappes indicates at least partial surface exposure of the Biharia Nappe System during Late Cretaceous times. Weathered surfaces were removed from the sample material before starting the separation procedure.

Paleontology, 1, 2, Peer reviewed, ISI periodicals 1. 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. Eoalpine Cretaceous very low-to low-grade metamorphism recorded on the illite-muscovite-rich fraction of metasediments from South Tisia eastern Mt Papuk, Croatia Geol Carpath.

From nappe stacking to exhumation: Cretaceous tectonics in the Apuseni Mountains (Romania)

However, the absence of metamorphic overprint in the Western part of the Bihor Unit precludes significant overthrusting. 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.

E-directed shear zones Fig. Contemporaneous or slightly delayed upper crustal detachment faulting and associated hanging-wall sedimentation of Late Cretaceous syn- to post-tectonic sediments occurs in the same extensional context.

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.

Rapid Late—Early 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. Associated kinematic indicators suggest top-NW nappe transport during D2 Figs. Brittle detachment faulting D3. Although no post-tectonic sediments directly overlie the Bihor and Codru Nappes in the study area, Geoloogia Cretaceous sediments were deposited in close vicinity Fig.

gomaniei 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. Our kinematic observations show top-W-directed deformation under brittle conditions Fig. 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.

Geological Society of Romania; 5. However, it shows a discordant age spectrum and is significantly older than other Alpine ages from the same unit. Differences in timing of cooling between the tectonic units relate to their structural position in the nappe stack.
