Natural Stone - QUARTZITE

Quartzite is a hard, metamorphic rock which was originally sandstone. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica content of the rock provides little to form soil from and therefore the quartzite ridges are often bare or covered only with a very thin soil and little vegetation.
