• Silicate mineral - Wikipedia

    en.wikipedia.org/wiki/Silicate_minerals Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of the Earth's crust.. In mineralogy, silica (silicon dioxide) SiO 2 is usually considered a silicate mineral. Silica is found in nature as the mineral quartz, and its polymorphs.. On Earth, a wide variety of silicate minerals ...
  • silicate mineral | Definition & Types | Britannica

    www.britannica.com/science/silicate-mineral Silicate minerals can be thought of as three-dimensional arrays of oxygen atoms that contain void spaces (i.e., crystallographic sites) where various cations can enter. Besides the tetrahedral (4-fold coordination) sites, 6-fold, 8-fold, and 12-fold sites are common.

    www.sciencedirect.com/topics/earth-and-planetary-sciences/silicate-mineral Silicate minerals such as clays and feldspars in sandstone pores are normally removed using mixtures of HF and HCl, whereas carbonate minerals are usually attacked with HCl. The chemical reactions are summarized in Table 16.1.The amount of acid required to dissolve a given amount of mineral is determined by the stoichiometry of the chemical reaction.

    www.nps.gov/subjects/geology/minerals.htm Micas are another group of silicate minerals composed of varying amounts of potassium, magnesium, iron, aluminum, silicon and water. All micas form flat, sheet like crystals that peel apart along one cleavage plane into individual smooth flakes. Biotite (pictured to the left) is a black or brown mica; muscovite is light-colored or clear mica.
