摘要

Abstract

The radiocarbon dating age of different components will give different results from the same sample. The carbonate is easily contaminated by both old carbonate and modern carbon. The effects of contamination are intricate and fascinating. The effects of old carbonate and modern carbon crisscross each other. Measuring samples at the level of δ13C can show the degree of contamination of the sample. Maybe the effect on the samples in CK1/81 core from modern carbon in ground water is minimal. If this is correct

the S3 salt layer was formed forty thousands years after the sediments were deposited. The14C dating ages of organic matter are reliable

and the14C dating ages of the total organic matter represent the age of the sediments. The14C dating age of the lower clay layer of gypsum and halite layer in LF82/8 core is 5870±200 years. If this is correct

the main salt layer in Lake Frome might have been formed 5870 years after the sediments were deposited.
