• Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone.
• Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases, is an opaque, impure variety of silica, usually red, yellow, brown or green in color; and rarely blue.
• The mechanics of eraillure formation are related to the propagation of a Hertzian cone of force through the cryptocrystalline matrix of the stone, but the particulars are poorly understood.
• Generally speaking, tools that require a sharp edge are made using cryptocrystalline materials that fracture in an easily controlled conchoidal manner.
• Ground stone tools are usually made of basalt, rhyolite, granite, or other cryptocrystalline and igneous stones whose coarse structure makes them ideal for grinding other materials, including plants and other stones.
• It is cryptocrystalline, consisting of fine intergrowths of the silica minerals quartz and moganite.
• The mechanical properties of the rhyolite on Mount Kineo exhibits the physical properties of flint and was used extensively by indigenous peoples to make arrowheads and implements and thus, has often been referred to as "Kineo flint" in literature; but this term misleads by implication that the rhyolite is a cryptocrystalline form of the mineral quartz derived from a sedimentary origin.
• Chrysoprase, chrysophrase or chrysoprasus is a gemstone variety of chalcedony (a cryptocrystalline form of silica) that contains small quantities of nickel.
• Hälleflinta under the microscope is very finely crystalline, or even cryptocrystalline, resembling the felsitic matrix of many acid rocks.
• Novaculite, also called Arkansas Stone, is a microcrystalline to cryptocrystalline rock type that consists of silica in the form of chert or flint.
• The iron oxides are typically hematite or magnetite with ilmenite, while the silicates are predominantly cryptocrystalline quartz as chert or jasper, along with some minor silicate minerals.
• A form of cryptocrystalline quartz (chalcedony) that is regarded as a semiprecious gemstone, agate is found in several areas in the state.
• Iddingsite is a pseudomorph that usually has crystals rimmed by a thin zone of yellowish brown or greenish cryptocrystalline material.
• The Dogger consists of cryptocrystalline limestones, bioclastic limestones and oolithic limestones spanning the period Upper Bajocian and Bathonian.
• This is a cryptocrystalline form of silica, consisting of fine intergrowths of the minerals quartz and moganite.
• The Lower Portlandian — generally composed of 35 m of well-bedded cryptocrystalline micrites — takes up the major part of the anticline.
• Some of the exotic materials included: cryptocrystalline quartz, blue-green nodular chert, Dover chert, novaculite, quartz, vein quartz, chalcedony, Horse Mountain agate, sandstone, hematite, steatite, slate, green slate, banded slate and igneous rock.
• Fairburns, like other types of agate, are composed of concentric layers of cryptocrystalline chalcedony colorized by different trace minerals.
• The minerals formed during the mercury mineralization, in rough order of abundance, are cinnabar, mercury, edgarbaileyite, metacinnabar, montroydite, eglestonite, calomel, an unidentified yellow massive cryptocrystalline mercury mineral, edoylerite, wattersite, giannellaite, mosesite, deanesmithite, and one occurrence of szmanskiite.
