Silica (Quartz) | SpringerLink
Silica sand is made up of small grains of quartz, the result of the weathering of igneous, metamorphic, and sedimentary rocks and subsequent sedimentation. Flint is a hard, tough chemical or biochemical sedimentary rock. It is a form of microcrystalline quartz (chert). It often forms nodules in sedimentary rocks such as chalk and marine limestones.
