摘要:Abstract(#br)On the Chinese Loess Plateau, stable carbon isotope values for total organic matter (δ 13 C TOC ) from more than 10 loess/paleosol sequences since the last glacial/interglacial show generally consistent variations, with enriched values normally occurring in pale...

摘要:Abstract(#br)As an indicator for terrestrial paleovegetation, the stable isotopic composition of total organic matter (δ 13 C org ) in loess sediments has been widely used for paleoclimatic reconstruction in western Europe, the Great Plains of North America and the Chinese L...

摘要:Abstract(#br)This study examines the accumulation of major and trace elements in peat deposits in central Yunnan Province, southwestern China. The ashes of an approximately 2 m long core spanning 32.7–11.4 ka are analyzed to assess the elemental contributions of organic mate...

摘要:Abstract(#br)The evolution of the Asian summer monsoon (ASM) over the past 7500 years and regional human–environment interaction over the past 2000 years were investigated using high-resolution multi-proxy records from a well-dated sediment core (YJ Core) from the northern i...

摘要:Abstract(#br)Understanding the fractionation mechanisms of Mo isotopes and seeking the main hosts of light δ 98/95 Mo during chemical weathering of continental rocks is a prerequisite for constraining heavy δ 98/95 Mo input into rivers. This study investigates the Mo concent...

摘要:Abstract(#br)The exceptionally preserved Chengjiang Biota (Yunnan, China) is significant for understanding the rapid development of complex animal-rich ecosystems during the evolutionary radiation of the Cambrian. However, the ecological signal provided by the fossils captur...
