The 260 Ma Emeishan continental flood basalts (ECFB) occur in SW China and northern Vietnam. A 550-m-thick sequence of ECFB in Guizhou Province (SW China) is composed of 12 basaltic lava flows, each ranging from 10 to 140 m in thickness. All samples belong to the high-Ti basalts (TiO 2 = 1.9–4.4 wt....
