- •
K-feldspar pIRIR dating can be used to date loess sample to at least ∼150 ka in ACA.
- •
Loess in the ACA was deposited during the penultimate and last glaciation periods.
- •
Loess deposits and stalagmite growth are comparable at glacial-interglacial cycles.
- •
There is a climatic pattern of wet-warm (interglacials), dry-cold (glacials) in ACA.
- •
Depositional hiatuses of over 50 kyr occur in ACA loess sequences.
