Quartzite is a hard, metamorphic rock which was
originally sandstone. Through heating and pressure
usually related to tectonic compression within orogenic belts, the original quartz sand grains and
quartz silica cement were fused into one. Pure
quartzite is usually white to grey. Quartzites often
occur in various shades of pink and red due to varying
amounts of iron oxide. Other colors are due to
impurities of minor amounts of other minerals.
Ortho quartzite is a very pure quartz sandstone
composed of usually well rounded quartz grains
cemented by silica. Orthoquartzite is often 99% SiO2
with only very minor amounts of iron oxide and trace
resistant minerals such as zircon, rutile and
magnetite. Although few fossils are normally present
the original texture and sedimentary structures are
preserved.
