Radiocarbon dating : proceedings of the ninth international conference, Los Angeles and La Jolla, 1976

Uranium content has been measured in eighty-nine samples from core V29-179 from the North Atlantic. Uranium analyses have been performed by nondestructive neutron activation and by the rapid and precise method of counting delayed neutrons. The sediments display an inverse relationship between uranium and calcium carbonate. When the uranium results are expressed on a carbonate-free basis, the depth distribution is not uniform but has six maxima at various depths which appear to correlate stratigraphically with glacial episodes. Presumably these values are the result of increased continental erosion. The six events occur at approximately \(9000,30,000,60,000,85,000,130,000\) and 150,000 B.P. This detailed uranium profile may prove to be a useful tool for stratigraphic correlations in Pleistocene chronology.
