Late Holocene climatic changes revealed by mineralogical records from lacustrine core KS-2006 from Lake Kusai in the Hoh Xil area, northern Tibetan Plateau

A new study reveals distinct late Holocene climatic shifts on the northern Tibetan Plateau, with significant implications for understanding regional environmental changes. Analysis of mineral assemblages from Lake Kusai's sediment core KS-2006 indicates that aragonite content reflects temperature variations, while the emergence of salt minerals since 2150 cal BP signals rising lake salinity. The research identifies three key climatic phases: a warm period (3770–2550 cal BP), a gradual cooling phase (2550–2150 cal BP), and a cold, dry era with intensified wind activity (2150 cal BP–present), punctuated by a notable warm interval between 900–700 cal BP. The study leverages mineralogical records to reconstruct past climate conditions, offering insights into the interplay between temperature, salinity, and wind dynamics in this ecologically sensitive region.
