Figure F15. Photomicrograph showing a lithology from Subunit IIIB (Sample 194-1193A-40X-1, 2 cm; 214.8 mbsf). This skeletal grainstone consists mainly of bryozoan fragments and subordinate benthic foraminifers (B), red algae (R), and bivalves (M). Bioclasts are fringed by isopachous fine prismatic calcite cement (1), and interparticle space is mostly infilled by later fine blocky calcite spar (2).
