Vibracore 3V1, Kailua Bay

Uniform burrowed to bioturbated, very fine- to fine-grained, Halimeda-bearing carbonate sand; massive appearing owing probably to extensive bioturbation; yellowish gray (5Y8/1); poor to fair sorting; clasts angular to subrounded; sand composed mainly of mix of Halimeda (30.0-36.0%, coral fragments (15.5-17.5%), calcareous algal fragments (10.5-12.0%) and benthic foraminifera (4.0-14.0%),with abundant unidentifiable clasts (12.5-14.5%) owing to fine grain size, and common carbonate rock fragment grains (2.5-12.0%); also minor mollusks (3.0-3.5%), echinoderm fragments (2.0-3.5%), calcareous sponge spicules (2.0-2.5%) and altered volcanic rock fragment grains (0.5-2.5%). A relatively sharp to burrow-mottled contact. Uniform burrowed to bioturbated, very fine- to coarse-grained, carbonate sand; massive appearing owing probably to extensive bioturbation; light olive to yellowish gray (5Y6/1-8/1); very poor sorting; clasts angular to subangular; sand composed mainly of mix of coral fragments (20.5-27.5%), Halimeda (15.5-26.0%), calcareous algal fragments (18.5-20.0%) and benthic foraminifera (12.0-16.5%),with common carbonate rock fragment grains (7.5-13.0%); minor unidentifiable clasts (3.5-5.0%) mollusks (1.5-7.0%) and echinoderm fragments (2.0-2.5%).
