abstract = {The Tatra Mts form the highest part of the Carpathian mountain chain; however, their tectonic and thermal evolution is still debatable. Previous magnetic fabric studies have primarily focused on the crystalline basement and its autochthonous cover. We investigate the magnetic fabrics of Cretaceous marly limestones from a Mesozoic nappe unit and post-thrusting Oligocene shales and mudstones to unravel the most recent tectonic evolution of the Tatra massif. In addition to standard petromagnetic measurements such as the acquisition of the Isothermal Remanent Magnetization or temperature-dependent susceptibility analyses, we investigated the paleotemperature of the Tatra region because high temperatures are known to significantly affect the magnetic mineralogy. The most common minerals in the studied units are paramagnetic phyllosilicates which govern the in-phase Anisotropy of Magnetic Susceptibility. The ferromagnetic fraction is represented by fine-grained magnetite with a minor contribution of hematite. Measured and counted vitrinite reflectances document an eastward increase in maturity, which is also reflected in the magnetite–hematite grain size ratios. Because the paleotemperatures recorded in the Cretaceous rocks follow the same increasing trend as the post-thrusting shales, it appears that both units were affected by a single major thermal event linked presumably to the Late Oligocene/Early Miocene burial. We propose that magnetic fabrics carried by phyllosilicates document the impact of crucial tectonic phases such as Miocene uplift and Cretaceous thrusting, whereas the out-of-phase Anisotropy of Magnetic Susceptibility and Anisotropy of Anhysteretic Remanent Magnetization fabrics most likely record the stress orientation during major burial episodes. Finally, the conspicuous vertical ferromagnetic lineation present in some Cretaceous sites documents the transpression-controlled tectonic regime in the Oligocene–Early Miocene. © 2024 Elsevier B.V.},

abstract = {Central Carpathian Paleogene Basin (CCPB; Central Western Carpathians) comprises mainly Oligocene clastic autochthonous age-equivalents of the widely known Menilite shale formation from the Outer Carpathians. However, little is known about the paleoenvironment and its subsequent changes during the basin's evolution. Furthermore, the available hydrocarbon potential data are based on anachronous methods and are not investigated on the sub-basin level. Gas chromatography-mass spectrometry (GC–MS) analyses supported by Rock-Eval data along with petrographic measurements enabled us to identify and document the paleoenvironmental evolution of the Orava sub-basin (NW remnant of CCPB). Thermal maturity based on vitrinite reflectance, 22S/(22S + 22R) homohopane ratio and 20S/(20S + 20R) sterane ratio increases from N to S and from Upper to Lower Oligocene. In the least mature samples ββ-hopanes, hopenes, and oleanenes are present, whereas in the most mature deposits less thermally stable compounds dissapeared. This maturation trend is shown also by the Rock-Eval data. Terrestrial organic matter input is documented by the predominance of III- and II/III-type of kerogen and the occurrence of several biomarkers, such as 3,3,7-trimethyl-1,2,3,4-tetrahydrochrysene, cadalene, retene, and perylene. The significant contribution of polycyclic aromatic hydrocarbons (PAHs) may be linked with wildfire-related land degradation and following runoff to the basin. Based on the measured fusinite reflectance values the wildfire types could range from hotter crown fires to colder surface fires. Depositional conditions in Lower Oligocene units are characterized by intermittent euxinia, as derived from small (<5 μm) pyrite framboid diameters and the presence of isorenieratane. Subsequently, a change of conditions to oxic/dysoxic in younger units is observed, and the input of terrestrial organic matter increased. © 2023},

abstract = {The Chočské vrchy Mts. are a part of the Tatra-Fatra Belt located in the Central Western Carpathians (Slovakia). We characterize the main Late Cretaceous-Cenozoic deformation events and the changing strain that formed the geological setting of the Chočské vrchy Mts. by applying the Anisotropy of Magnetic Susceptibility coupled with the Anisotropy of Anhysteretic Remanent Magnetization and complemented by petromagnetic analyses. We analyse Lower Cretaceous marly limestones of the Mraznica Formation (Fm.), which is a part of the Krížna nappe, and the “post-thrusting” Eocene-Oligocene Huty Fm. Petromagnetic experiments reveal that paramagnetic minerals control the magnetic susceptibility, although a distinct contribution of ferromagnetics (magnetite; hematite and likely pyrrhotite) is also documented. The magnetic fabric in both the Mraznica and Huty fms. is generally sedimentary with minor tectonic imprint. The NNE-SSW orientation of the magnetic lineation in most of the Mraznica Fm. sites corresponds well with the local bedding strike as well as the calculated regional statistical fold axis for the Krížna nappe, but it deflects from the expected orientation considering the regional Cretaceous thrusting direction. Similarly oriented magnetic lineation is also documented in some Huty Fm. sites. Magnetic and structural results reveal the dip of the post-trusting Paleogene strata covering the Chočské vrchy Mts. horst block differs from both the dip of magnetic lineation and the dip of statistical fold axis from the Krížna nappe within this uplifted block, suggesting complex uplift-related deformations. We conclude that Krížna nappe folds together with AMS lineation, both formed during Late Cretaceous thrusting, have been later rotated by an angle of 20° as an effect of Neogene transpression, which also affected the magnetic fabric of the post-thrusting cover. © 2022 Sciendo.
