Pedogenic carbonates of loess-paleosol sequences
 Máslo, Jaroslav ; Flašarová, Kristýna (advisor) ; Šefrna, Luděk (referee)
Loess is sediment composed predominantly os silt-size particles. Silt-size particles are transoported mainly by wind. Loess covers 10 % of earth surface. If the loess can be layed for a longer time when the glacials and interglacials alternate, the loess-paleosol sequences are created. Common part of loess and loess-paleosol sequences are pedogenic carbonates, which are particles of CaCO3. There are many types of carbonates, e.g. Calcified root cells. hypocoatings, needle-fiber calcite… Loess-paleosol sequences and carbonates in them are realy useful source of information about paleoenvirnonment. In practicle part of this work the isotopic composition of C and O in pedogenic carbonates from loess-paleosol sequence in Dejvice (Prague) was measured.
