Reconstructed ~13-ka paleoclimate indexes using the Chibuzhang Co sediments on the central Qinghai-Tibet Plateau_CH

We developed two regional paleoclimate indexes for assessing summer monsoon effect in the source region of the Yangtze River (central Qinghai-Tibet Plateau). The Indian Monsoon Index (IMI) was created by averaging TOC and TIC records, while the effective moisture index (EMI) was obtained by averaging mean size grade MG (φ) and TIC after normalizing these three proxies. The sequence is long ~13,000 years.
