Vibracore 19V1, Leeward coast

Uniform succession of vaguely-laminated to bioturbated, fine- to medium-grained, foraminiferal/algal/coral carbonate sand: massive appearing owing probably to extensive bioturbation; light olive to olive gray (5Y6/1-4/1); moderate sorting (2-4% scattered shell fragments; 2-3 mm diameter); sand size clasts subangular to rounded; composed mainly of a mix of foraminifera (30.5%), calcareous algae (25.5%), coral fragments (23.5%); common volcanic rock fragments (5.5%); minor carbonate rock fragments (3.0%) and echinoid fragments (3.0%). Massive-appearing (bioturbated), medium- to coarse-grained, algal/coral/foraminiferal carbonate sand: light olive to olive gray (5Y6/1-4/1); poor sorting (4-6% scattered shell fragments; 2-5 mm diameter); sand size clasts subrounded to rounded; composed mainly of a mix of calcareous algae (38.5%), coral fragments (24.5%) and foraminifera (10.5%), with abundant volcanic rock fragments (9.0%) and carbonate rock fragments (9.0%); note distinct specimens of the small solitary coral Cycloseris fragilis.
