Similar to those in Nasilai tempers (Rewa Delta, Fiji). Common plutonic quartz grains, altered and calcic plagioclase grains, K-feldspar,hornblende and clinopyroxene. Sands of probable fluvial origin volcanic and metavolcanic rocks with felsitic to microlitic internal textures; sedimentary and metasedimentary rocks including microgranular siltstone or hornfels, foliated slate or phyllite, chert, and argillite; and microgranular hypabyssal or plutonic igneous rocks.
