This is the most important organization of minerals. Silicates are crafted from metals blended with silicon and oxygen. There are greater silicates than all other minerals put together.The mica at the left is a member of this group.
Kaolinite is a clay mineral with chemical composition Al2Si2O5(OH)4. It is an important industrial mineral. Rocks rich in kaolinite are called kaolin. Kaolinite, common group of clay minerals that are hydrated aluminum silicates; they contain the main components of kaolin (china clay). The group includes kaolinite, which is chemically similar but amorphous to kaolinite, and its rarer forms, stalagmite and nacrite, halloysite and allophane.
Spodumene is a pyroxene member of inosilicate mineral with chemical formula is LiAl(SiO3)2, lithium aluminium. It can also be pink, lilac, or green. Crystals are prismatic, flattened, and typically striated along their length. Gem varieties of the mineral usually exhibit strong pleochroism.
Phlogopite is a member of mica group family of phyllosilicates mineral. Color is a yellow, greenish, or reddish-brown. It is the magnesium endmember of the biotite stable answer series, with the chemical formulation KMg3AlSi3O10 (F, OH) 2.
Beryl is a member of cyclosilicate minerals with composed of beryllium aluminium. Chemical formula: Be3Al2Si6O18. Few people have ever heard of the mineral beryl but almost everyone has heard of its principal gemstone varieties emerald and aquamarine.
Tremolite is a silicate mineral and member of the amphibole group. Chemical formula is Ca2(Mg5.0-4.5Fe2+0.0-0.5)Si8O22(OH)2. A calcium magnesium silicate, tremolite forms a solid-solution series with ferroactinolite, where iron substitutes in increasing amounts for magnesium.
Nosean, otherwise called Noselite, is a mineral of the feldspathoid type in tectosilicate with formula: Na8Al6Si6O24 (SO4). H2O. It frames isometric precious stones of...
Diopside is a member of pyroxene group mineral with formula is MgCaSi2O6. Specimens can be colorless but are more often bottle green, brownish green, or light green in color. It has two distinct prismatic cleavages at 87 and 93° typical of the pyroxene series. Diopside occurs in the form of equant to prismatic crystals that are usually nearly square in section.
Lazurite is a member of sodalite group in feldspathoid mineral also it is tectosilicate with formula is (Na,Ca)8[(S,Cl,SO4,OH)2|(Al6Si6O24)]. A sodium calcium aluminosilicate, lazurite is the main component of the gemstone lapis lazuli and accounts for the stone’s intense blue color
Sodalite is a feldspathoidal tectosilicate mineral that is rich royal blue widely used as an ornamental gemstone. Chemical formula is Na8 (Al6Si6O24) Cl2. Specimens can be blue, gray, pink, colorless, or other pale shades. They sometimes fluoresce bright orange under ultraviolet light. Sodalite nearly always forms massive aggregates or disseminated grains.
Leucite is a feldspathoid mineral in group of tectosilicate. It is a rock forming mineral include potassium and aluminium tectosilicate, formula is K.Specimens can...
Nepheline is the most common feldspathoid mineral in the world, its name from the Greek word nephele, which means “cloud” a reference to the fact that the mineral becomes cloudy or milky in strong acids. Specimens are usually white in color, often with a yellowish or grayish tint.
Zeolite is a group of silicate minerals that a family of hydrated aluminosilicate minerals that contain alkali and alkaline-earth metals with unusual properties with importance industrial application. Zeolite form is usually well-formed crystals with pale colors and generally soft and can easily crushed.They are found in geologically young volcanic fields.
