The parent rock for quartzite is quartz-rich sandstone. As sandstone becomes deeply buried, rising temperature will fuse the quartz grains together forming the extremely hard and weather-resistant rock quartzite. Like marble, quartzite comes in many colors, but when pure it is light-colored.
Quartzite tends to have a sugary appearance, and when broken the fractures cut through the sand grains, not around them as with a sandstone.
