A COMPARISON: PALAEOENVIRONMENTAL CHANGE RECORDS OF CHINESE LESS AND ANTARCTIC ICE CORES OVER LAST 150,000 YEARS

摘要

Studies on Chinese loess and a comparison with Antarctic ice cores provided a general pattern of global environmental change and the regional differentiation over last 150,000 years. Climatic change revealed by magnetic susceptibility of Linxia loess section in China was paralled with temperature variation revealed by SD of Vostok ice core over last 150,000 years, which indicates a pattern of climatic change tendencies on a longscale (thousand years). However, the ranges of variation at the same phase, especially, during the last Interglacial age (80,000-140,000 a.B.P.) were more different between Chinese loess sections and Antarctic ice cores.
