Quartzite Rock Geology and Uses - ThoughtCo

WebMicroscopic quartz crystals often form chert seams and nodules as silica-rich groundwater moves through a variety of sedimentary and metamorphic rocks. Chert precipitated from silica-rich groundwater can also replace bone and wood present in sediment and sedimentary rocks, often even preserving the materials’ original cellular structure. WebChert has four diagnostic features: the waxy luster, a conchoidal (shell-shaped) fracture of the silica mineral chalcedony that composes it, a hardness of seven on the Mohs scale, and a smooth (non-clastic) sedimentary texture.
