Essay / Research Paper Abstract

A 5 page paper discussing these rare forms of silica. Generally only found in areas where quartz rocks have been subjected to extremely high pressure such as in Arizona's Meteor Crater, stishovite was first discovered in sandstone that had been converted to glass as a result of the impact of the meteor. While both are silica, coesite's structure is that of tetrahedrons; stishovite is constructed of octahedrons with oxygen. Stishovite is the densest known form of silica and also the hardest known oxide; both begin to degrade in the absence of high pressure. Bibliography lists 8 sources.
