Climatic and environmental changes recorded in Baahar Nuur Lake core in the Ordos Plateau dataset (Holocene)
CTR :139
Key words Baahar Nuur Lake,Climatic,environmental changes
Relevant data A 5.3 m lake core was drilled in Baahar Nuur Lake in the Ordos Plateau, and measurements of mean grain size, organic δ13C (δ13Corg), organic carbon content (TOC), C/N, carbonate content, carbonate δ13C (δ13Ccar) and δ18O (δ18Ocar) were conducted for retrieving the Holocene chronosequence of climatic changes based on 15 AMS14C dates. The record documented four major stages of climate change in the Ordos Plateau: (IV) a cold and dry condition before ~7.65 14C ka BP; (III) a warm and humid stage between ~7.65 and ~5.40 ka BP; (II) a generally drier and cooler climate since ~5.40 ka BP with two humid events occurring from ~4.70 to ~4.60 ka BP and from ~4.20 to ~3.70 ka BP, and (I) a dry climate characterized by complete desiccation of the lake after 3.70 ka BP. Stage III can be further divided into three sub-stages: (IIIa) a warm and humid episode from ~7.65 to ~6.70 ka BP, (IIIb) a warm and relatively dry episode from ~6.70 to ~6.20 ka BP, and (IIIc) the magthermal and maghumid episode of the Holocene from ~6.20 to ~5.40 ka BP.
