Late Pleistocene lithofacies, paleolimnology and ostracode fauna of kettles on the Illinoian till plain, Illinois, U.S.A

The response of sediment, vegetation and aquatic environments to climate change during the last glacial--interglacial--glacial intervals were investigated from fossiliferous successions in four breached kettle basins in south-central Illinois. The thickest measured successions of lacustrine/paludal sediment per basin include 16.4 m (Raymond Basin), 9.0 m (Bald Knob Basin), 7.0 m (Pittsburg Basin) and 4.3 m (Hopwood Farm). The age of calcareous, fossiliferous sediment is beyond the limits of the radiocarbon method, but leached, organic-rich sediments at Pittsburg Basin and Bald Knob Basin yielded ages that span from about 45 ka to 21 ka yr B.P. Electron spin resonance analyses on Sangmonian tooth enamel from Hopwood Farm indicate an age between 73 to 137 ka.
