Geochemical Characteristics of Major Elements in Holocene Loess-Paleosol Sequence in the Eastern Guanzhong Basin,Shaanxi,China
|
Abstract:
Based on the field investigation,sampling and major elements analysis in a Holocene loess-paleosol profile in the eastern Guanzhong basin of Shaanxi Province,the major element geochemical characteristics are discussed.The results show that the content of major elements is mainly made of SiO2,Al2O3and CaO,and their total concentrations is up to 77.41%,the element content is followed by SiO2>Al2O3>CaO>Fe2O3>MgO>Na2O>K2O>TiO2.Relatively to loess L1,Ca,Na have strongly leached out of the paleosol S0 but K,Fe,Al...
