The last interglacial: paleotemperatures and chronology.
The O(18)/O(16) analysis and Th(230)/Pa(231) dating of deep-sea cores showed that the last interglacial age, with an early major temperature maximum followed by two smaller ones, extended from 100,000 to 70,000 years ago and was preceded by a glacial age extending from 120,000 to 100,000 years ago. The O(18)/O(16) analysis and Th(230)/U(234) dating of speleothems confirm and refine these ages.
