Determination of the age of carbonate rocks by the cosmogenic chlorine-36 in the valleys of Miętusia and Mała Łąka

Abstract

The Mietusia and Mała Łąka valleys were glaciated at the turn of the Holocene and Pleistocene, with the maximum extent during the Last Glacial Maximum (LGM). This was one of the assumptions of the project, which we wanted to prove by dating glacial forms. Both valleys are situated in the Western Tatras. This part of the Tatra Mountains is much less studied in terms of the age of glacial and postglacial forms compared to the forms from the High Tatras. We used the cosmogenic 36Cl because of the geological structure of the study area, which consists is mainly of Triassic dolomites and limestones with very limited meade of gneiss and other metamorphic rocks at the highest picks (Krzesanica 2122 m a.s.l., Małołączniak 2096 m a.s.l., Ciemniak 2096 m a.s.l.). The Tatra Mountains are northernmost alpine orogen which was glaciated are a kind of palaeoclimatic link the of southern Europe Central Eastern the palaeoclimate for these glaciers seems a necessity. The Tatra Mountains junction continental oceanic temperature amplitudes and the highest precipitation in the summer months. The high amount of
