Holocene hydroclimate data from Almalou Peatland

Almalou Peatland (37.66° N, 46.63° E) is located in the western Iranian Plateau in WA. A long sediment core (AM18E) was collected from the center of Almalou Peatland, and its chronology was established based on 16 AMS ¹⁴C dates. The chain length of <i>n</i>-alkanoic acids was interpreted as a hydroclimate indicator based on a proxy validation study. This record reveals a wetting trend during 9-7.5 cal ka BP, a mid-Holocene hydroclimate optimum (7.5-3 cal ka BP), and a rapidly drying trend during 3-0 cal ka BP.
