Abstract


The new method of absolute dating by (cosmogenic isotope 36Cl) is considered. The method is based on measuring concentrations of isotope 36Cl which is produced in terrestrial rocks exposed at the surface to cosmic radiation. The presence of 36Cl in most of the rocks and its long half-life make it useful in determination of the age of landforms and sediments in different depositional environments within the time range from a few thousand years to about one million years. The initial samples collected in the Polish Tatra Mts. are being analyzed in the U.S.A. The authors believe that cosmogenic 36Cl method becomes a new important tool in Quaternary chronostratigraphy of Poland.
