摘要

Multidisciplinary studies conducted along two geodynamic test transects across the Polish segment of the Western Carpathians, crossing the Orava Basin in the west and the Pieniny Klippen Belt and Magura Nappe along the Dunajec River valley in the east, included gravity and geodetic surveys as well as geological investigations. Gravity and geodetic surveys were carried out annually in years 2004-2006. Their results appear to suggest recent subsidence of the Orava Basin, particularly intensive in a Quaternary graben in the northern part of the area, confirming conclusions derived from geomorphic analyses. Data obtained for the Dunajec River transect do not show any particular differentiation among individual benchmarks, what can point to either minor uplift of the entire area, minimal differences between successive slices of the Magura Nappe and the Pieniny Klippen Belt, or both. Horizontal displacements of benchmarks, different for the western and eastern transects, towards the west and SW as well east and SE, respectively, can result from general uplift of the area comprised between these transects. On the other hand, the N to NNE-oriented vectors of recent horizontal motions, observed for stations located south of the Pieniny Klippen Belt, point to the ongoing NNE-directed push of the ALCAPA block.
