Flint is a hard, tough chemical or biochemical sedimentary rock that breaks with a conchoidal fracture. It is a form of microcrystalline quartz that is typically called chert by geologists. It often forms as nodules in sedimentary rocks such as chalk and marine limestones.Novaculite  is another similar material.
