ArticleMegadrought and cultural exchange along the proto-silk road
Graphical abstract
The δ13C, δ18O and Sr/Ca series of a stalagmite from Kyrgyzstan, provide so far, the highest-resolved (~3 yr) and most precisely-dated (~6‰) precipitation record in Arid Central Asia covering the middle to late Holocene. The record reveals a 640-yr megadrought between 5820 and 5180 a BP, which likely delayed prehistoric trans-Eurasian cultural exchange along the proto-Silk Road.
