Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica content of the rock provides little material for soil; therefore, the quartzite ridges are often bare or covered only with a very thin layer of soil and little (if any) vegetation.
Mining, processing and transporting sand generate large quantities of silica dust, which is notorious for the damage it does to the lungs and respiratory system when inhaled. In recent years, the dramatic expansion of hydraulic fracturing and horizontal drilling technology to extract gas and oil, commonly called "fracking," has led to boom in sand mining across the upper

AST''s Silica Quartzite Mines AST''s quarry mine is in production exploiting nearsurface semiconsolidated sandstone lithologies. This resource sits in a small package that is a remnant of the Ecca group, consisting of sandstone, that itself overlies the Loskop formation that consists of quartzites that are a target resource for roadstone.
The three major forms of crystalline silica quartz, tridymite and cristobalite are stable at different temperatures and have subdivisions. For instance, geologists distinguish between alpha and beta quartz. When low temperature alpha quartz is heated at atmospheric pressure it changes to beta quartz .
