Abstract

The Holy Cross Mountains, located in the southern part of the central Poland, possesses especially interesting features for geological studies, particularly, the role of the long-lived Holy Cross Fault and the timing of tectonic evolution are still to be evaluated. Throughout the combined use of the thermochronology and structural modelling software, the tectonic evolution of the area is achieved . In particular, low-temperature thermochronometers have been widely used, as (U-Th)/He analysis and fission tracks analysis, both performed on apatites. The samples collected in situ have been worked to obtain fitting crystals for the analysis. Thermochronological ages have been used to constrain and clarify the structural evolution inferred by maps and geological profiles. The type and rate of movement along the Holy Cross Fault during its geological history was quantified. The construction of the model shows the great significance of Devonian subsidence in the area, as well as the importance of Variscan orogeny. Dispersion of the data suggests that the Mesozoic burial history was slow and multiphase. The results testify the role of Laramide orogeny and the lack of significant phases after that
