Quartz : . Statut : Minéral agréé par l'I.M.A. Le quartz est le polymorphe de SiO 2 le plus répandu. Les autres polymorphes sont la tridymite, la cristobalite, la coesite et la stishovite ; ils forment la famille de la silice ; famille à laquelle on rattache l'opale.Le quartz est isostructural avec le phosphate berlinite..

Quartzite - Wikipedia

Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts.Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of iron oxide (Fe 2 O 3).Sandstone |Composition, Properties, Formation, Chemical Composition of sandstone usually quartz framework grains are the dominant mineral in clastic sedimentary rocks. Because of they have exceptional physical properties such as hardness and chemical stability.Physcial properties of these quartz grains survive multiple recycling events and also allowing the grains to display some degree of rounding.
