Chinese loess and the paleomonsoon
Web摘要：. This paper presents a general review of the recent research advances of the East Asian paleomonsoon, based mainly on studies of the loess-soil sequences in the Chinese Loess Plateau. In the last 2.6 million years, the paleomonsoonal history may be divided into about 166 events on a time scale of the Earth's orbital variations.
