Sherd BN1 from Banda Naira Islet (Neira). Slide WD_17_12 from Dickinson Collection, Bishop Museum. x4 Magnification PPL (left) XPL (right). Scale bar: 0.5mm. High resolution image or full slide in VIMIPO (user: Guest pwd: Guest). Imaged by K. Hardy and M. Leclerc, ANU.

Pyroxene-bearing (but hornblende free) feldspathic sands with dominant volcanic rock fragments are pumiceous felsic glass. Contain vitroclastic glass shards of vocanic ash in the past.
