Uniform succession of massive-appearing (bioturbated), very fine- to medium-grained, algal/coral/foraminiferal carbonate sand: massive appearing (no obvious sedimentary structures) owing to extensive bioturbation; yellowish gray (5Y8/1) to light olive gray (5Y6/1) above; well sorted (2-5% scattered shell fragments); sand size clasts angular to subrounded; composed mainly of a mix of calcareous algae (26.0-37.0%) coral fragments (22.5-28.0%) and foraminifera (14.5-25.0%); abundant Halimeda (7.5-15.0%), common carbonate rock fragments (2.5-3.5%); minor echinoid fragments (2.5-3.0%).
