摘要
米图西亚谷和Mała Łąka谷在全新世和更新世之交被冰川覆盖,末次盛冰期(LGM)被冰川覆盖的程度最大。这是该项目的一个假设,我们想通过确定冰川形态的年代来证明这一点。这两个山谷都位于西塔特拉。与高塔特拉山脉相比,这部分的塔特拉山脉在冰川时代和冰川后形态方面的研究要少得多。由于研究区地质构造以三叠系白云岩和灰岩为主,最高采点(Krzesanica 2122 m a.s.l, Małołączniak 2096 m a.s.l, Ciemniak 2096 m a.s.l)片麻质和其他变质岩含量极少,因此选用了宇宙成因36Cl。塔特拉山脉是最北端的高山造山带,冰川是一种古气候联系,欧洲南部,中欧,东部,这些冰川的古气候似乎是必要的。塔特拉山脉连接了大陆海洋温度振幅和夏季降水最多的地区。大量的
Determination of the age of carbonate rocks by the cosmogenic chlorine-36 in the valleys of Miętusia and Mała Łąka
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
