摘要
Mineral magnetic measurements have been made on Quaternary Red Earth profilesfrom Zhejiang Province, Eastern China. Three distinctive magnetic stratigraphic horizons havebeen identified on the basis of magnetic susceptibility, anhysteretic remanent magnetization,saturation isothermal remanent magnetization and magnetization parameters measurements.Magnetic measurements revealed that there were great variations in ferrimagnetic mineralconcentration, mineralogy assemblages and grain size in Quaternary Red Earth profiles, suggestingthat these variations reflect pedogenic processes fluctuation and environmental changes. Thepreliminary results indicate that mineral magnetic measurement of Quaternary Red Earth is usefulfor studying the Quaternary environmental changes recorded in paleosols.
