Abstract. In terms of petrochemical and trace-element data, basalts from the axial rift valley are suggested to originate from sources of the sub-continental lithospheric mantle, inhomogeneity of which was due to extracting upper and lower crustal components. Trace-element modeling indicated 3-8 %partial melting of apatite-bearing sources with varying garnet and clinopyroxene proportions.
Keywords: сenozoic, basalt, Baikal rift, trace elements.
