The lower, Mszana Dolna, unit comprises several W-E trending folds, overturned and thrust-faulted at the window’s edges.
Niższa jednostka, Mszany Dolnej, składa się z kilkunastu równoleżnikowych fałdów, przy brzegu okna obalonych i złuskowanych.
The thrusting of the Magura unit led to tectonic slicing of the top parts of folds in its floor.
Nasuwająca się jednostka magurska spowodowała złuskowanie wyższych partii fałdów podłoża.

the thrust slicing? Moreover, it is not unlikely that the thrust slicing within the outcrop belt might bring up slivers of graptolitic rock from Silurian strata of the subjacent Roberts Mountains - https://goo.gl/boezB7

After many years of speculations about heavy thrust slicing of the crust, supposedly recorded in seismic reflection images (e.g., in the Appalachians - https://goo.gl/gvxnSC

Considering complex thrust slicing mapped along the trace of the thrust, the thickness may be original or tectonic - https://goo.gl/Tl3AR7

An orogen may be almost completely eroded away, and only recognizable by studying (old) rocks that bear traces of orogenesis. Orogens are usually long, thin, arcuate tracts of rock that have a pronounced linear structure resulting in terranes or blocks of deformed rocks, separated generally by suture zones or dipping thrust faults. These thrust faults carry relatively thin slices of rock (which are called nappes or thrust sheets, and differ from tectonic plates) from the core of the shortening orogen out toward the margins, and are intimately associated with folds and the development of metamorphism - https://en.wikipedia.org/wiki/Orogeny#Erosion

Thrust duplex

Duplexes occur where there are two decollement levels close to each other within a sedimentary sequence, such as the top and base of a relatively strong sandstone layer bounded by two relatively weak mudstone layers. When a thrust that has propagated along the lower detachment, known as the floor thrust, cuts up to the upper detachment, known as the roof thrust, it forms a ramp within the stronger layer. With continued displacement on the thrust, higher stresses are developed in the footwall of the ramp due to the bend on the fault. This may cause renewed propagation along the floor thrust until it again cuts up to join the roof thrust. Further displacement then takes place via the newly created ramp. This process may repeat many times, forming a series of fault bounded thrust slices known as imbricates or horses, each with the geometry of a fault-bend fold of small displacement. The final result is typically a lozenge shaped duplex. - https://en.wikipedia.org/wiki/Thrust_fault#Thrust_duplex
