Three partial nappes occur within the Subtatric zone in the eastern part of the Tatra Mts. These are (from base to top or from south to north respectively): (1) the lower Subtatric partial nappe sensu stricto corresponding to the Suchy Wierch unit of the Zakopane Subtatric area, (2) the Bielskie Tatry partial nappe (= the Hawrań digitation of Sokołowski, 1950) and (3) the Jastrzębia Turnia-Palenica partial nappe (= the Bujaczy digitation of Andrusov, 1936). Their lithostratigraphic completeness and tectonic character differ depending on their situation on transversal elevations and/or depressions, respectively. At the Hawrań-Jagnięcy elevation only the Bielskie Tatry nappe is more or less completely preserved. It is thrust onto the tectonically reduced Middle Triassic of the lower Subtatric nappe. The Bielskie Tatry nappe is superposed by the Jastrzębia Turnia-Palenica nappe which contains the Middle-Upper Triassic members and the Fatra Formation. Farther west, in the Szeroka Jaworzyńska depression (in the Jaworzyna subtatric area), the lower Subtatric nappe is represented by two tectonic scales, namely the Holica-Zadnia Kopa and the Czerwona Skałka ones. Both units show but a part of the Middle Triassic carbonate sequence, and a complete Jurassic and Lower Cretaceous sequence (the latter is reduced at its top). These lower Subtatric scales are overlaid by the Tatry Bielskie nappe and this, in turn, by the Jastrzębia Turnia-Palenica partial nappe. On the Koszysta transversal elevation, still farther west, the lower Subtatric nappe is reduced to a few very small scales. It is overlaid there by a tectonically overturned Kopy Sołtysie unit, a part of the Bielskie Tatry nappe. The Kopy Sołtysie unit is tectonically covered by the Triassic carbonates of the Jastrzębia Turnia-Palenica partial nappe along the line: Gęsia Szyja - Filipczański Wierch. A continuation of the lower Subtatric nappe eastward, up to the Jaworowa Valley, is documented. The Triassic formations cropping out at Filipczański Wierch, Gęsia Szyja, Łysa Skałka, and Wierch Skałki are included to the Jastrzębia Turnia-Palenica partial nappe. Tectonic affiliation of several small tectonic scales of the Križna nappe (sensu lato) in the Gęsia Szyja-Kopy Sołtysie area remains an open question.
