WD_90_4

Sherd Len4 from Lenger (Lenger). Slide WD_90_4 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. Imaged by K. Hardy and M. Leclerc, ANU.

Non-calcareous volcanic temper of lithic sand. Moderately sorted and subrounded medium to coarse temper sands displaying placer concentration of opaque iron oxide grains (probably magnetite), glassy rock fragments, and clinopyroxene. Temper probably from stream.
