Compared with mineral contents of Core ZC1 (b) and Core ZC2 (a) and records of floods and sediment input of the Yangtze River and the Yellow River over the Holocene (Compared with Zhou and Yu, 2013). The ancient flood events were mainly concentrated in the Yangtze River basin over three periods: 7.5–6.5 ka, 5.0–3.5 ka and 1.0–0.5 ka. In the Yellow River basin, the flood events were mainly concentrated in 4.2–2.8 ka and 1.5–0.8 ka. This is consistent with the provenance of the detrital and clay minerals.
