WebJun 3, 2006 · The Emeishan Large Igneous Province (ELIP) cover large areas in SW China and Northern Vietnam and include the Emeishan continental flood basalts (ECFB) (Song et al. 2001) and mafic–ultramafic intrusions that have been dated at 260 Ma (Zhou et al. 2002a, 2006; Guo et al. 2004 ). WebThe age of the Emeishan lavas in SW China remains poorly constrained because the extrusive rocks are (1) thermally overprinted and so represent an open system . ... We interpret this age as the termination age of the Emeishan flood basalts. The age of the Guadalupian-Lopingian boundary is still unconstrained by high-resolution geochronology …
Emeishan flood basalt: mantle plume uplift not the culprit?
WebMay 31, 2024 · The Emeishan large igneous province (ELIP) of SW China is considered to be one of the best examples of a mantle plume derived continental flood basalt province ( Chung and Jahn, 1995; Chung et al., 1998; He et al., 2003; Xu et al., 2004; Ali et al., 2005; Campbell, 2005; Shellnutt, 2014 ). WebThe Emeishan flood basalt is a large igneous province erupted during the Permian–Triassic period in southwestern China. Based on petrographic, major and trace element, and Sr–Nd isotope data, the Emeishan basalts can be classified into two major magma types. These are: 1 a low-Ti LT type that exhibits low TiŽ. bruce chirre
