    THE CARPATHIAN RIVER SYSTEM IN ROMANIA – GENESIS AND EVOLUTION by MIHAI IELENICZ, LAURA TÎRLĂ

    Published 2012-07-01
    “…In establishing the formation stages of different generations of Carpathianvalley systems, some general conditions have been taken into consideration (formation of the mountain systemby tectonic movements; the evolution of marginal base levels, significantly influencing the intensity of linearand headward erosion; the orographic structure – a relatively ring-like mountain system built of groups of massifs andtectonic basins; the evolution of morpho-climatic systems). …”

    $\mbox {}^{40}$Ar/$\mbox {}^{39}$Ar geochronology of crustal deformation by Monié, Patrick, Münch, Philippe, Milesi, Gaétan, Bonno, Michael, Iemmolo, Arthur

    Published 2023-05-01
    “…Crustal deformation is characterized by brittle and ductile faults that accommodate at different scales the strain imposed by plate tectonics. The aim of this contribution is to show with the help of different examples how the in situ $\mbox {}^{40}$Ar/$\mbox {}^{39}$Ar dating of synkinematic neocrystallized minerals in ductile shear zones and the step-heating $\mbox {}^{40}$Ar/$\mbox {}^{39}$Ar dating of synkinematic authigenic clays in fault gouges can bring information on the timing of fault activity. …”

    SUPPLEMENTARY TO THE COMPOSITION OF THE URAL BERYLS AND INCLUSIONS OF SYNGENETIC MINERALS IN THEM by V.I. Popova, V.A. Popov, M.A. Rassomakhin

    Published 2023-12-01
    “…The presence of fractures and regenerated fragments of early beryl indicates synmineralization tectonics. In beryl from the Mariinsky deposit, the previously unknown syntactic ingrowths of bavenite and zones of parallel columnar aggregates of co-crystallization of beryl and bavenite, as well as late pyrite, fluorite, gismondine-Ca and tobermorite, are identified. …”

    New paleomagnetic data on the Permian-Triassic sedimentary sections of the Moscow syneclise by A.M. Fetisova, R.V. Veselovskiy, M.P. Arefiev

    Published 2020-06-01
    “…Presumably, the reasons are (a) an inclination shallowing in the studied sedimentary rocks, (b) the presence of a significant contribution of non-dipole components to the main geomagnetic field about 250 million years ago, (c) local tectonics. The results of this study can be of considerable interest for clarifying the paleogeographic position of the East European Platform and testing the hypothesis of tectonic rigidity of Eurasia. …”

    Published 2017-04-01
    “…Gomishan mud volcano phenomenon in the southeastern edge of the Caspian Sea, given its oil and gas resources, has been studied by some geologists in terms of geology and tectonics but not in terms of microbiology. Accordingly, it seems necessary to study this phenomenon from the perspective of microbiology in order to identify prokaryotes living in this area. …”
