Fig. 9From: Biomass burning history in East Asia during the last 4 million years recorded in elemental carbon variability at IODP site U1423LR04 standard benthic δ18O (Lisiecki and Raymo 2005) and C6/EC in fine and coarse fractions. The significant maxima observed in the higher temperature biomass burning proxy (C6/EC) in coarse and fine fractions are marked as blue and red vertical lines corresponding to glacial and interglacial stages, respectivelyBack to article page
