The study of sediments and speleothems in the Zbrašov Aragonite Caves
Bosák, Pavel ; Šlechta, Stanislav ; Hercman, H. ; Pruner, Petr
The numerical dating of hydrothemal speleothems (doughnuts) from locality At Crocodile gave older data than was published in the literature: 123 to 127 thousand years (with range 108 to 144 thousand years). Speleothems crystallized in the time of climatic optimum of the last interglacial period (Eemian) corresponding to the marine isotope stage (MIS) 5e. Clastic sediments from excavations in the area At Crocodile show normal paleomagnetic polarity in all samples with nearly recent magnetic field directions. Studied sediments cover block of hydrothermal speleothems fallen from the wall and therefore they must be younger than 108 thousand years.
Aplication of environmental magnetic methods in sedimentary rock research deposited in the Ochozská Cave (Moravian Karst)
Kadlec, Jaroslav ; Šlechta, Stanislav
V Ochozské jeskyni (Moravský kras) byly detailně ovzorkovány dva profily jeskynními sedimenty pro účely environmentálně magnetických analýz.
Age and genesis of sediments in the Ochozská Cave
Kadlec, Jaroslav ; Pruner, Petr ; Venhodová, Daniela ; Hercman, H. ; Nowicki, T.
Large section in cave deposits are exposed in the Ochozská Cave in southern segment of the Moravian Karst. The study of the genesis and age of these cave deposits poses a clue to the reconstruction of development of the Ochozská Cave and of local paleohydrographic history. The time of deposition was determined by probably deposited during the Middle and late Pleistocene in the cave.
