Geochronology of core TC11–1.
The age model is obtained from the interpolation between 14C ages (filled pink triangles) of plant and cellulose samples of the upper peat section (47–270 cm; Table S1) and the OSL ages (filled blue circles) of the middle lacustrine sediment section (Table S2). Grey cross squares show the 14C ages based on total organic matter (not used in the age model; see text). The cross symbol (red) denotes the volcanic eruption age at surrounding areas (~46,000–50,000 BP)20,21. The yellow filled triangle shows the transition age from MIS-4 to MIS-3 inferred from the speleothem δ18O curve at Sanbao Cave (~59,560 BP)24. Horizontal filled columns show the lithology of core TC-11–1.
