Upper Cenozoic Glacial History South of the Grand Banks of Newfoundland
A 10 m long piston core from a ridge on the continental rise south of the Grand Banks consists of foram-nanno ooze with several clay rich intervals. Microfossils and magnetic stratigraphy show that the upper part of the sequence is Brunhes in age, and disconformably overlies upper Pliocene sediments...
