Phenocrysts are >0.5 mm except for magnetite where >0.1 mm. X indicates >5% by volume; < indicates 1%-5%; - indicates not present. N indicates that the silicate phenocrysts were tabulated in Sites 790/791, table 11 of Taylor, Fujioka, et al. (1990, doi:10.2973/odp.proc.ir.126.1990), but the thin sections were unavailable for further study. Parentheses indicate some alteration. Units are the shipboard igneous stratigraphic units (Taylor, Fujioka, et al., 1990).
