Abstract
The aim of this work was to establish the structure of a crystalline basement along the previously constructed regional cross-section located in the westernmost part of the Polish Outer Carpathians. The analysis of the gravity and magnetic data, additionally constrained by the borehole information, geological maps and seismic profile was carried out to anticipate the depth to the crystalline basement. Based on the qualitative interpretation, several basement-rooted faults were delineated that in some cases most probably affected the structural evolution of the Carpathians Fold and Thrust Belt. Moreover, along the entire cross-section, the basement seems to be located much deeper than previously anticipated. Lastly, the 2D potential fields modelling indicates that a continuous sedimentary cover, most probably represented by the Devonian and Carboniferous sequence or Miocene sediments of the Carpathian foredeep, may be expected below the Carpathian nappes along the whole cross-section length.
期刊介绍:
The Journal of Geosciences is an international peer-reviewed journal published by the Czech Geological Society with support from the Czech Geological Survey. It accepts high-quality original research or review papers dealing with all aspects of the nature and origin of igneous and metamorphic rocks. The Journal focuses, mainly but not exclusively, on:
-Process-oriented regional studies of igneous and metamorphic complexes-
Research in structural geology and tectonics-
Igneous and metamorphic petrology-
Mineral chemistry and mineralogy-
Major- and trace-element geochemistry, isotope geochemistry-
Dating igneous activity and metamorphic events-
Experimental petrology and mineralogy-
Theoretical models of igneous and metamorphic processes-
Mineralizing processes and mineral deposits.
All the papers are written in English, even though they may be accompanied by an additional Czech abstract. Each contribution is a subject to peer review by at least two independent reviewers, typically at least one from abroad. The Journal appears 2 to 4 times a year. Formally it is divided in annual volumes, each of them including 4 issues.
