Nontronite :: Nontronite (n.) A greenish yellow or green mineral, consisting chiefly of the hydrous silicate of iron..
Bole :: Bole (n.) Any one of several varieties of friable earthy clay, usually colored more or less strongly red by oxide of iron, and used to color and adulterate various substances. It was formerly used in medicine. It is composed essentially of hydrous silicates of alumina, or more rarely of magnesia. See Clay, and Terra alba..
Zeolite :: Zeolite (n.) A term now used to designate any one of a family of minerals, hydrous silicates of alumina, with lime, soda, potash, or rarely baryta. Here are included natrolite, stilbite, analcime, chabazite, thomsonite, heulandite, and others. These species occur of secondary origin in the cavities of amygdaloid, basalt, and lava, also, less frequently, in granite and gneiss. So called because many of these species intumesce before the blowpipe..
Crocidolite :: Crocidolite (n.) A mineral occuring in silky fibers of a lavender blue color. It is related to hornblende and is essentially a silicate of iron and soda; -- called also blue asbestus. A silicified form, in which the fibers penetrating quartz are changed to oxide of iron, is the yellow brown tiger-eye of the jewelers..
Potassium :: Potassium (n.) An Alkali element, occurring abundantly but always combined, as in the chloride, sulphate, carbonate, or silicate, in the minerals sylvite, kainite, orthoclase, muscovite, etc. Atomic weight 39.0. Symbol K (Kalium)..
Unisilicate :: Unisilicate (n.) A salt of orthosilicic acid, H4SiO4; -- so called because the ratio of the oxygen atoms united to the basic metals and silicon respectively is 1:1; for example, Mg2SiO4 or 2MgO.SiO2..
Pimelite :: Pimelite (n.) An apple-green mineral having a greasy feel. It is a hydrous silicate of nickel, magnesia, aluminia, and iron..
Brewsterite :: Brewsterite (n.) A rare zeolitic mineral occurring in white monoclinic crystals with pearly luster. It is a hydrous silicate of aluminia, baryta, and strontia..
Apophyllite :: Apophyllite (n.) A mineral relating to the zeolites, usually occurring in square prisms or octahedrons with pearly luster on the cleavage surface. It is a hydrous silicate of calcium and potassium..
Glauconite :: Glauconite (n.) The green mineral characteristic of the greensand of the chalk and other formations. It is a hydrous silicate of iron and potash. See Greensand.
Silicon :: Silicon (n.) A nonmetalic element analogous to carbon. It always occurs combined in nature, and is artificially obtained in the free state, usually as a dark brown amorphous powder, or as a dark crystalline substance with a meetallic luster. Its oxide is silica, or common quartz, and in this form, or as silicates, it is, next to oxygen, the most abundant element of the earth's crust. Silicon is characteristically the element of the mineral kingdom, as carbon is of the organic world. Symbol Si. A
Pectolite :: Pectolite (n.) A whitish mineral occurring in radiated or fibrous crystalline masses. It is a hydrous silicate of lime and soda.
Thorite :: Thorite (n.) A mineral of a brown to black color, or, as in the variety orangite, orange-yellow. It is essentially a silicate of thorium..
Leucite :: Leucite (n.) A mineral having a glassy fracture, occurring in translucent trapezohedral crystals. It is a silicate of alumina and potash. It is found in the volcanic rocks of Italy, especially at Vesuvius..
Serpentine :: Serpentine (n.) A mineral or rock consisting chiefly of the hydrous silicate of magnesia. It is usually of an obscure green color, often with a spotted or mottled appearance resembling a serpent's skin. Precious, or noble, serpentine is translucent and of a rich oil-green color..
Zoisite :: Zoisite (n.) A grayish or whitish mineral occurring in orthorhombic, prismatic crystals, also in columnar masses. It is a silicate of alumina and lime, and is allied to epidote..
Cyanite :: Cyanite (n.) A mineral occuring in thin-bladed crystals and crystalline aggregates, of a sky-blue color. It is a silicate of aluminium..
Enstatite :: Enstatite (n.) A mineral of the pyroxene group, orthorhombic in crystallization; often fibrous and massive; color grayish white or greenish. It is a silicate of magnesia with some iron. Bronzite is a ferriferous variety..
Datolite :: Datolite (n.) A borosilicate of lime commonly occuring in glassy,, greenish crystals..
Chlorite :: Chlorite (n.) The name of a group of minerals, usually of a green color and micaceous to granular in structure. They are hydrous silicates of alumina, iron, and magnesia..
