The isotope composition of authigenic and biogenic carbonates and diatom silica are
commonly used as palaeoclimate proxies from lake sediments. This article reviews the …

There is great uncertainty over the timing and magnitude of the termination of the African
Humid Period (AHP). Spanning from the early to middle Holocene, the AHP was a period of …
