摘要:Abstract(#br)The long-term cooling or warming trend is one of the most important aspects of Holocene paleoclimatic research. However, there are currently significant discrepancies among climatic simulation results, sedimentary and synthesized Holocene temperature records. Th...

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...

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)Mo isotopic composition in large rivers is very important for understanding global Mo cycle. At present, temporal variation signatures in the δ 98/95 Mo in large rivers have not been investigated, which hinder a comprehensive understanding on the mechanism for t...

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)Bioactive trace elements play an important role in metabolic processes and, ultimately, marine productivity. An understanding of the complex interactions between biogeochemical processes and trace elements in reef ecosystems is important for establishing geochemical ...

摘要:Abstract(#br)El Niño–Southern Oscillation (ENSO) has a strong influence on the climate of the Changjiang River basin, China, most notably upon extreme events such as flooding and drought. However, long-term historical records, which reveal the impacts of ENSO variability on ...

摘要:Abstract(#br)Lake Huguangyan (21°9′ N, 110°17′ E), a maar lake located near the South China Sea, can provide valuable sedimentary data regarding past changes of the East Asian monsoonal system. Here, we used the proxies of TOC, δ 13 C org , δ 15 N, and leaf wax n -alkan...
