| Abstract: | The global climatic variations during the past 2.5 million years were perfectly recorded by the sequence of loess paleosoil developed loess plateau in China.Chinese loess is regarded as one of the best archives of climate and environment changes during the Quaternary.The current state and progress of loess grain size were expounded.The paper summarized the grain size,magnetic susceptibility and so on,further investigated the loess deposit and its record of climate and environmental changes. |
