Quartzite was originally a sandstone that underwent metamorphism, resulting in a harder and more compact rock with a high quartz content. During the metamorphic process, the sandstone was subjected to heat and pressure, causing the quartz grains to recrystallize and cement together, forming quartzite.

Quartz was used in the Stone Age to make tools like hand axes and scrapers because of its hardness and ability to be chipped into sharp edges. It was readily available in many regions and was a valuable resource for early humans in tool-making. Quarzite, a metamorphic rock made from quartz, was also used in tool-making for its durability and resistance to wear.
