摘　　要：This study used trace elements in olivine as a new petrogenetic indicator to further constrain the petrogenesis of potassic basalts from the Erkeshan-Wudalianchi-Keluo-Xiaogulihe potassic volcanic field （EWKX for short） in the Songliao Basin of NE China,with a combination of the previous olivine and whole-rock geochemical data.This study used trace elements in olivine as a new petrogenetic indicator to further constrain the petrogenesis of potassic basalts from the Erkeshan-Wudalianchi-Keluo-Xiaogulihe potassic volcanic field （EWKX for short） in the Songliao Basin of NE China,with a combination of the previous olivine and whole-rock geochemical data.
