DATING OF HOLOCENE DEPOSITS BY THE RADIOCARBON METHOD AND BY POWER ANALYSIS (in Russian)
The age of the large Holocene deposits which are scattered throughout the territory of the USSR with the exception of the deserts and mountainous areas, was determined by C/sup 14/ dating. Peat samples from single layers taken from the Berendeevo marshes, 100 km NE from Moscow were used for the tests. The location of the layers was determined by drilling, using the samples for a comparison of age measurements by stratigraphy and by the BETA activity of the radiocarbon with the help of a proportional counter. Results showed a marked increase of the age with depth. it was noted that the trunk of a pine tree lying at a depth of 2.25 to 2.50 m had the same absolute age of 4730 plus or minus 190 years as peat samples taken from the same depth. Roots from the same depth but a certain distance away, lying in an old quarry showed an age of only 3630 plus or minus 165 years. The systematic study of the age of individual layers by the radiocarbon method and comparison with data obtained from stratigraphic studies is an important tool for establishing the exact boundaries between the Pleistocene and Holocene deposits.
