Figure F17. Summary of basement stratigraphy in Hole 1256D, cored during Expedition 309, showing (from left) a depth scale, core numbers, recovered intervals, unit and subunit boundaries, igneous lithology, locations of glass and altered glass (solid/stippled line), groundmass grain size, and phenocryst percentage based on thin section descriptions. cx = cryptocrystalline, ol = olivine, plag = plagioclase, cpx = clinopyroxene. The Leg 206 stratigraphy is slightly revised according to the Leg 206 VCD records.
