Extended Data Fig. 5: Carbonate and plant wax stable isotopes.
From: Proto-monsoon rainfall and greening in Central Asia due to extreme early Eocene warmth
Stable isotope record (δ18Ocarb and δ13Ccarb) of the vadose-grown and pedogenic carbonates and δ2Hwax values of plant waxes. δ18O values of the soil water (δ18Owater) are reconstructed using the Δ47-derived temperatures. Modern-day δ18Owater values of the summer monsoon and wintertime westerlies are shown57.
