Quartzite – Formation Composition Properties and Uses ...

Quartzite (from German Quarzit) forms when quartz sandstones are metamorphosed. The term quartzite also implies its high quartz content. Most quartzites contain 90% quartz by volume but the percentage can go up to 99% in the case of the purest quartzite forms. Quartzite looks similar to its parent rock but it is much harder than sandstone.
