A multi-proxy record of environmental changes during the Holocene from the Haolaihure Paleolake sediments, Inner Mongolia

This figure indicate the comparison of Haolaihure Paleolake result (using TOC as an example) with other regional records (Xiao et al., 2006; Wen et al., 2010) in Inner Mongolia, speleothem δ18O record from Dongge Cave (Dykoski et al., 2005), and the central Asia moisture index (Chen et al., 2008). The Haolaihure Paleolake record and Hulun Lake record (A/C, ratios of Artemisia to Chenopodiaceae) are similar to those from Daihai Lake and Dongge Cave in early and mid-Holocene, but to the central Asia moisture index record in late Holocene. The similarity suggests that the climatic conditions in the Haolaihure Paleolake area were primarily controlled by variations in the ASM prior to 3.7 cal ka BP but by Westerlies after that.154
