Controls on PGE fractionation in the Emeishan picrites and basalts: Constraints from integrated lithophile–siderophile elements and Sr–Nd isotopes

Picrites from the Emeishan large igneous province (ELIP) may be divided into those that show LREE enrichment and those that are characterized by LREE depletion. All picrite types have low 87Sr/86Sr ratios (
