Geochemical characterization of the Luochuan loess-paleosol sequence, China, and paleoclimatic implications

Autor: Bor-ming Jahn, Sylvain Gallet, Masayuki Torii

Publikováno v: Scopus-Elsevier

Chemical (major and trace element) and isotopic (Sr, Nd) analyses of the Luochuan loess-paleosol sequence in China were performed in order to examine the following problems: (1) potential source heterogeneity; (2) element behavior during pedogenesis;
