Opaque iron oxide grains, and vitric volcanic rock fragments composed of mafic sideromelane (basaltic glass). The calcareous grains are skeletal and micritic (pelletal) debris of modern reefal origin, and the calcareous aggregates are well sorted sands with textures appropriate for a beach origin.
Olivine placer sand. Clinopyroxene dominant, but minor orthopyroxene.
Olivine placer sand.
Quartz. Vitric.
Also called SVMAP118. Basaltic sand temper.

Plagioclase-rich non-placer temper. Stream origin. Non-Lapita.
Lapita sherd. Plagioclase-rich non-placer. Calcareous grains appear to be reworked limeclasts, rather than modern reef detritus. Stream origin.
A pyroxene-rich (plagioclase-poor and lithic-poor) placer. Stream origin.
Plagioclase-poor and pyroxene rich temper. Non-Lapita sherd. Stream origin.
