Figure F21. Photomicrographs of igneous features of sedimentary rocks in Unit III, Hole U1349A. A, B. Probable ferroandesite clast in conglomerate with abundant feldspar and skeletal titanomagnetite (Thin Section 205; Sample 324-U1349A-7R-1, 65–67 cm). C, D. Small chip of probable ferroandesite in conglomerate, with trachytic texture in feldspar and abundant skeletal titanomagnetite (Thin Section 204; Sample 324-U1349A-7R-1, 40–46 cm). E, F. Palagonitized hyaloclastite sandstone with (E) angular chips of both glass (orange) and spherulitic basalt (dark brown) and (F) possible lithic chips of more crystalline basalt (Thin Section 206; Sample 324-U1349A-7R-1, 112–115 cm). A, C, E, and F are under transmitted light; B and D are under reflected light.
