摘要
The thick loess strata in the Loess Plateau of China, which have not been essentially reformed by internal and external agents, are one of the optimum continental deposits preserving the extraterrestrial materials in the last 2.5 Ma. Thus, combining the records with the detailed data of the loess-paleosol sequence, the ages and environmental impacts of the astrogeologic events can be determined.
