摘要
The F/Cl ratio for loess and palcosol has been studied based on the difference in the geochemical behaviour of fluorine and chlorine under hypergene conditions. The variation of F/Cl ratio in the loess section indicates a paleoclimatic evolution from humid to arid since loess accumulation. The maximum F/Cl ratio is found .in the fifth paleosol layer, reflecting an optimum climatic period for pedogenesis. The variation of F/Cl ratio is synchronous with the climatic fluctuation from warm-humid to arid-cold.
The F/Cl ratio for loess and paleosol has been studied based on the difference in the geoehemical behaviour of fluorine and chlorine under hypergene conditions. The variation of P/Cl ratio in the loess section indicates a paleoclimatic evolutioli from humid to arid since loess accumulation. The maximum F/Cl ratio is found in the fifth paleosol layer, reflecting an optimum climatic period for pedogenesis. The variation of F/Cl ratio is synchronous with the climatic fluctuation from warm-humid to arid-cold.
