WATA5_12 — Sherd WATA5-12 from Watinglo (Aitape coast). Slide WD_80_2 from Dickinson Collection, Bishop Museum. x4 Magnification PPL (left) XPL (right). Scale bar: 0.5mm. High resolution image (user: Guest pwd: Guest) or full slide in VIMIPO with higher exposure. Imaged by K. Hardy and M. Leclerc, ANU.

Dominant plagioclase feldspar and hornblende varieties are the only ferromagnesian silicate grains, some rock fragments with glassy to felsitic (devitrified glass) internal textures, moderately sorted, subangular to subrounded, fine to medium volcanic sand of probable fluvial origin.
