Rejestr zmian klimatycznych późnego glacjału i holocenu w obrębie torfowiska pod Kotoniem (Beskid Średni, Karpaty zewnętrzne)

On the southern slope of the pass located between Kotoń Mt. and Pękalówka Mt. (Beskid Makowski Mts), a colluvial vast landslide surrounded by two wedge-shaped niches occurs. At the foot of one of these niches, a longitudinal depression (gutter pipe type) filled up with a fen type peat bog was formed. The maximum depth of these deposits is about 4.7 m. At the bottom there occurs silt with gravel and a thin layer (10 cm) ofstrongly decomposed peat (dated at 12I40 š70 BP by a 14C method) and covered with clayey silt (4.18-3.85 m). This is overlain by moss fen and sedge-moss fen type peat (3.85-1.2 m) covered, in turn, bv a thick mineral laver (1.2-0.2 m) composed of clay and silty clay. The profile ends with a thin level of sedge peat. Mineral cover was deposited in some stages; the first was ascribed to a wet period of the Boreal-Atlantic phase boundary, whereas the main was assigned to the Early Subboreal, and the Subatlantic phase. The radiocarbon datings, confirmed by a pollen analysis, indicate that the landslide depression formed during the Bfiling Interstadial. The peat accumulation started with the Older Dry as and the Allerfd Interstadial. The deposition of mineral (non-organic) layers that underlie the peat bog was linked to the wet phases recorded in the Early Atlantic. Early Subboreal. and Early Subatlantic.
