摘要
The oxygen isotope composition of foraminifera in deep-sea sediments has provided so far the most accurate record for the Pleistocene Epoch. It revises the traditional concepts about the glacial-interglacial (cold-warm) stages in the Quaternary climate and has become the basic stratigraphic tool as compared with other methods. Since the evolution of the Quaternary climate has great influence on the life of human beings and the geological environment, oxygen isotope stratigraphy has been established and used extensively in investigations of the history of events in the deep-sea core.
