The paper presents the first data on geochemistry (major and trace elements, isotopes) of the Late Devonian-Early Carboniferous basalts of the Char suture-shear zone in East Kazakhstan, and includes detailed analysis of their geological relations and petrogenesis (fractional crystallization/melting modeling). Three groups of oceanic basalts coexist in the Char zone. Group 1 basalts are associated with oceanic siliceous sediments and have medium TiO2, relatively flat REE patterns (La/Smn = 0.7, Gd/Ybn = 1.3), Zr/Nbav. = 42 and eNdav. = 6.3. in a mid-oceanic ru.
