PHYSICAL, CHEMICAL AND MINERAL PROPERTIES OF THE POLONNARUWA STONES [PDF]

SPIE Proceedings, 2013
We report on the physical, chemical and mineral properties of a series of stone fragments recovered from the North Central Province of Sri Lanka following a witnessed fireball event on 29 December 2012. The stones exhibit highly porous poikilitic textures comprising of isotropic silica-rich/plagioclase-like hosts.
