Huaying Pianyanzi area is located in the middle-east of Sichuan Basin. The newly discovered Pianyanzi Late Permian basalt is between Maokou Formation (underlying) and Longtan Formation (overlying), which can be compared with Emeishan basalt. The study of petrology, mineralogy and geochemistry suggests that Pianyanzi basalts belong to the high-Ti alkaline series, and the rare earth element (REE) and trace element patterns are similar to those typically found in ocean island basalts (OIB). The basalts have not undergone any significant crustal contamination. The crystallization temperature of clinopyroxene is estimated to be 1 405~1 439℃, suggesting anomalously thermal inputs from a mantle source and a possible plume-head origin. The REE simulation result su-ggests that Pianyanzi basalts were produced by small degree of partial melting of Emeishan mantle plume within the garnet-spinel transition region. In general, the Pianyanzi Late Permian basalt is very similar to the Emeishan basalt, especially the basalt in the east of Emeishan Large Igneous Province (ELIP), which is an integral part of ELIP.
