Heavitree quartzite (HQ) starting material.

Heavitree quartzite (HQ) starting material from Australia. Non-porous quartzite, with ~1% impurities (muscovite, feldspar and iron oxides), and equant grains with average diameter ~200 mm. Intragranular water ~0.2 wt%, mostly in the form of fluid inclusions. Diagenetic overgrowths visible.
