The 50 pages that link to Quartz, each with the reason it gives.

• Calcium carbonateCompared with: Quartz can resemble carbonate rock but has a silicate composition and different chemistry.

• Silicate mineralBroader topic: Quartz is a framework silicate made entirely of silicon and oxygen.

• GraniteRelated: Its abundant grains are a defining component of granite.

• Mohs scaleBroader topic: It is a common reference point in the scale’s harder range.

• SandstoneRelated: Its durability makes quartz grains especially likely to survive transport and accumulate in sandstone.

• PorcelainRelated: It contributes silica to porcelain bodies and helps control shrinkage during firing.

• PiezoelectricityBroader topic: Quartz was among the crystals in which the Curies first observed the effect.

• Silicon dioxideBroader topic: It is the best-known natural crystalline form of silicon dioxide.

• Clay mineralCompared with: Quartz commonly occurs alongside clay minerals but lacks their layered structure and surface behavior.

• PegmatiteRelated: Quartz is a frequent constituent of granitic pegmatites.

• FluoriteCompared with: Quartz may resemble fluorite in color, but it is much harder and lacks cleavage.

• Pierre CurieRelated: Quartz crystals enabled the Curie brothers' experiments on piezoelectricity.

• Placer depositCompared with: Quartz commonly forms the lighter sediment fraction from which dense placer minerals are separated.

• Quartz clockBroader topic: Its piezoelectric properties and stable resonance make it the clock’s timing element.

• Cosmogenic nuclide datingRelated: Quartz hosts measurable beryllium-10 and aluminum-26, making it a standard target mineral.

• Cleavage (crystal)Compared with: Quartz lacks cleavage and instead commonly breaks with a conchoidal fracture.

• Optically stimulated luminescenceRelated: Quartz grains trap radiation-produced electrons that light can release during OSL measurement.

• GneissRelated: Quartz often forms light-colored bands in gneiss.

• Mineral identificationBroader topic: Quartz demonstrates how one mineral can vary widely in color while retaining diagnostic properties.

• SiltRelated: Quartz grains are common constituents of silty sediment.

• OrthoclaseCompared with: Quartz commonly occurs beside orthoclase in granite but has different chemistry and cleavage.

• Crystal oscillatorRelated: Quartz is the material most commonly used to set oscillator frequency.

• QuartziteRelated: Quartz grains dominate quartzite and recrystallize into its interlocking texture.

• Silicon–oxygen tetrahedronBroader topic: The simplest fully connected framework, and the purest form of the tetrahedral network.

• Thermoluminescence datingRelated: Quartz grains can store radiation-induced charge and produce thermoluminescence signals.

• ChertNarrower topic: Chert is made chiefly of quartz in crystals too small to see individually.

• SandBroader topic: Its durability makes quartz grains common in sand deposits.

• Trigonal crystal systemBroader topic: Quartz is a familiar mineral whose crystal structure belongs to the trigonal system.

• DioriteRelated: Diorite generally contains little quartz; abundant quartz points toward granodiorite instead.

• Rhombohedral crystal systemBroader topic: Its trigonal symmetry links a familiar mineral to this crystal classification.

• SpodumeneRelated: Quartz is a frequent pegmatite companion and may occur alongside spodumene.

• TonaliteRelated: Quartz is abundant in tonalite and helps define its classification.

• GranodioriteRelated: Its abundance is one of the defining features of granodiorite.

• GreisenBroader topic: Quartz commonly remains abundant as feldspar is altered during greisenization.

• MyloniteRelated: Quartz-rich layers often show the recrystallized grains used to study mylonitic deformation.

• TourmalineCompared with: Quartz shares common geological settings with tourmaline but lacks its boron-bearing chemistry.

• RecrystallizationBroader topic: Quartz develops diagnostic recrystallized textures in many deformed crustal rocks.

• FeldspathoidCompared with: Quartz marks silica saturation and is incompatible with feldspathoids at equilibrium.

• Fused quartzRelated: High-purity quartz supplies the silica melted to make this glass.

• Hexagonal crystal familyBroader topic: Its trigonal symmetry exemplifies the less obvious system included in this family.

• WollastoniteRelated: Quartz or other silica sources provide silicon for wollastonite-forming reactions.

• ChalcedonyRelated: Intergrown microscopic quartz crystals form much of chalcedony’s structure.

• DaciteRelated: Quartz commonly occurs in dacite and signals its silica-rich composition.

• Iceland sparCompared with: Quartz can also be birefringent, but its optical behavior differs from calcite's strong splitting.

• Tectosilicate frameworkBroader topic: The pure-silica framework case, needing no charge balance at all.

• Brittle–ductile transition zoneRelated: Quartz-rich crust can begin ductile flow at different conditions from stronger dry rocks.

• ChrysoberylCompared with: Quartz cat’s-eye can show chatoyancy, but chrysoberyl cat’s-eye is generally harder and more valuable.

• Crystal skullNarrower topic: Many famous crystal skulls are carved from quartz, whose hardness affects how it can be worked.

• Potassium sodium tartrateCompared with: Quartz is another piezoelectric material, but its response does not depend on Rochelle salt’s hydrated double-salt lattice.
