| 161-975B-33X-2, 3-4 | Foraminifer-nannofossil ooze. | Grain- to matrix-supported. | Sand to clay. | Whole and fragmented planktonic foraminifers. | Quartz with Fe-coatings; zircon; glauconite; feldspar; phosphatic debris; quartz-mica tectonite lithic fragments. | Nannofossils; clay minerals; Fe-oxides; opaque minerals. | Carbonate and glauconite in foraminifers. |
| 33X-3, 143-144 | Carbonate-volcaniclastic lithic sandstone. | Grain- to matrix-supported; matrix-rich; well rounded to subangular grains. | Granule to clay. | Roughly equal proportions of volcanic and carbonate lithic fragments (black, tachylitic and altered microlitic and lathwork volcanic debris; micrite, oncolitic micrite, microsparite, biomicrosparite, pelletal micrite and microsparite, calcarenite); carbonate lithic fragments contain planktonic foraminifers and tintinnids(?). | Quartz; plagioclase; opaque minerals. | Silt-sized whole and fragmented foraminifers; altered glass; micrite; nannofossils (?); clay minerals. |
|
| 33X-CC, 9-10 | Biocalcarenite with terrigenous sand. | Grain-supported; laminated; moderately well sorted. | Sand. | Planktonic foraminifers; monocrystalline and polycrystalline quartz; lithic fragments of micrite, shale/slate, quartz-mica tectonite, polycrystalline mica. | Red algae; glauconite; phosphatic bone fragments(?); pellets; biotite; plagioclase; coarse carbonate; garnet; celestite(?). | Rare. | Microcrystalline celestite(?). |
| 33X-CC, 3-5 | Biomicrite with terrigenous sand. | Matrix-to grain-supported; laminated (alternating laminae are more bioclast- and quartz-rich). | Sand to clay. | Whole and fragmented planktonic foraminifers; monocrystalline and polycrystalline quartz; lithic fragments of shale/slate, siltstone, sedimentary chert, quartz-mica tectonite, polycrystalline mica, micrite, altered volcanic glass. | Echinoderm; phosphatic debris; biotite; plagioclase; coarse carbonate; garnet, fragments of shale/slate. | Micrite; clay minerals. | Common celestite protonodules(?). |
