Chemical Weathering Intensity and Terrigenous Flux in South China during the Last 90,000 Years—Evidence from Magnetic Signals in Marine Sediments

Abstract: The level of chemical weathering is strongly affected by climate. We presented magnetic properties associated with element ratios from the northern part of the South China Sea to denote links between chemical weathering intensity and monsoon changes in the previous 90,000 years. The magnetic parameter IRM AF80mT /SIRM, representing the variations of high coercivity minerals in marine sediments accompanied with the Al 2 O 3 /TiO 2 and the Chemical Index of Alteration (CIA), demonstrates strong chemical and phys… Show more

“…interval in PC338. Relatively low S –300 values occurred over glacial stages at other sites because of aerosol dust inputs (Chen et al, ) or strong weathering periods (Yang et al, ). These factors caused S –300 variations within a total limit of 0.06 over the past 36 kyr B.P., so terrestrial weathering influences cannot explain the low S –300 values over the ∼32–15 kyr B.P.…”
