Ages for the lacustrine and fluvio-deltaic Unit 1 are between ~70 and 110 ka, and generally point to deposition during MIS5. More specifically, however, the oldest obtained age of 110 ± 5 ka from Unit 1a falls into MIS 5d, while all remaining ages (~70e92 ka) in the near-shore lacustrine and fluvio-deltaic sediments of Unit 1b
fall into MIS5a/b, potentially suggesting that both sub-Units 1a and 1b may be separated chronologically. A radiocarbon age from Unit 1b yielded ~35 cal ka BP and indicates some degree of contamination with younger carbon introduced by recrystallization on the ostracod shells which were used for dating.
