Cenozoic alkali basalts,located in the central North China Craton, are main components of Cenozoic basalt province in the North China Craton. The Hebi basalts are basanites and alkali olivine basalts, belonging to alkaline rocks,with SiO2 contents of 45.0%~47.8%, MgO concentrations of 7.3%~8.5%, and Na2O+K2O abundances of 4.6%~6.3%. They are enriched in light rare earth elements(REEs) with highly fractionated LREEs and HREEs((La/Yb)N=15.1~21.2). It is concluded that the Hebi alkali basalts were derived from small degree partial melting of asthenospheric mantle at depths more than 80 km,with interaction with lithospheric mantle.
