10Be datování, 10Be datingThe 10Be exposure age method was applied to 21 samples of crystalline rocks from cirques, roches moutonnées, tors and glacial sediments in two valleys of the Giant Mountains in the Bohemian Massif: the Obrí dul and the Labský dul Valleys. Geomorphological evidence combined with 10Be dating shows that deglaciation occurred between (23.2 ± 3.8) (10Be) ka and (8.0 ± 1.5) (10Be) ka. Permanent ice and firn fields were still present in the upper parts of cirques and on plateaus up to around 3 - 4 thousand years ago.
