文摘
- •
The Mg isotopic composition of the Luochuan loess–paleosol sequence is measured.
- •
All samples are isotopically lighter than the UCC.
- •
Shifts in 未26Mg are controlled by changes in carbonate preservation.
- •
Loess sediments cannot be used to estimate the Mg isotopic composition of the UCC.
