Abstract
The O18/O16 analysis and Th230/Pa231 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 O18/O16 analysis and Th230/U234 dating of speleothems confirm and refine these ages.
