feldspar definition

  • noun:
    • any one of a small grouping of plentiful rock-forming minerals occurring principally in igneous, plutonic, many metamorphic stones, and comprising silicates of aluminum with potassium, salt, calcium, and, rarely, barium. About 60 per cent of the earth's outer crust is composed of feldspar.
    • some of a sizable number of rock-forming nutrients that, collectively, make-up about 60per cent regarding the planet's exterior crust. The feldspars are all aluminum silicates of alkali metals salt, potassium, calcium and barium. Feldspars are the principal constituents of igneous and plutonic rocks.
    • A name fond of a group of nutrients, closely relevant in crystalline form, and all silicates of alumina with either potash, soda, lime, or, in a single instance, baryta. They occur in crystals and crystalline public, vitreous in luster, and breaking rather easily in two guidelines at right angles to each other, or almost therefore. The colors usually are white or nearly white, flesh-red, bluish, or greenish.
    • In mineralogy, one of a rather common group of closely associated minerals, all silicates of aluminium, together with either calcium, salt, potassium, or in one instance barium.
    • any of a small grouping of difficult crystalline nutrients that include aluminum silicates of potassium or salt or calcium or barium
    • Any of several numerous rock-forming minerals happening principally in igneous, plutonic, plus some metamorphic stones, and comprising silicates of aluminum with potassium, salt, calcium, and, seldom, barium. About 60 percent regarding the earth's exterior crust comprises feldspar.
    • some of a sizable band of rock-forming minerals that, collectively, make up about 60per cent of the earth's exterior crust. The feldspars are typical aluminum silicates regarding the alkali metals sodium, potassium, calcium and barium. Feldspars will be the major constituents of igneous and plutonic rocks.
    • A name fond of a team of minerals, closely associated in crystalline form, and all silicates of alumina with either potash, soda, lime, or, in one single case, baryta. They occur in crystals and crystalline masses, vitreous in luster, and breaking instead quickly in two instructions at correct perspectives to one another, or almost so. The colors usually are white or almost white, flesh-red, bluish, or greenish.
    • In mineralogy, among a tremendously typical number of closely relevant nutrients, all silicates of aluminum, and either calcium, salt, potassium, or in one instance barium.
    • any of a team of hard crystalline minerals that contains aluminum silicates of potassium or salt or calcium or barium
    • some of a small grouping of plentiful rock-forming nutrients happening principally in igneous, plutonic, and some metamorphic stones, and composed of silicates of aluminum with potassium, salt, calcium, and, rarely, barium. About 60 percent of the planet's outer crust consists of feldspar.
    • some of a big selection of rock-forming nutrients that, together, comprise about 60% of earth's external crust. The feldspars are all aluminum silicates of this alkali metals salt, potassium, calcium and barium. Feldspars will be the main constituents of igneous and plutonic stones.
    • some of a team of plentiful rock-forming nutrients occurring principally in igneous, plutonic, plus some metamorphic rocks, and comprising silicates of aluminum with potassium, sodium, calcium, and, rarely, barium. About 60 per cent of this earth's exterior crust consists of feldspar.
    • any one of a big group of rock-forming nutrients that, collectively, make-up about 60percent of the earth's exterior crust. The feldspars are all aluminum silicates associated with the alkali metals sodium, potassium, calcium and barium. Feldspars would be the principal constituents of igneous and plutonic stones.
    • A name directed at a small grouping of minerals, closely related in crystalline type, and all sorts of silicates of alumina with either potash, soft drink, lime, or, in one situation, baryta. They occur in crystals and crystalline public, vitreous in luster, and breaking instead easily in two instructions at correct perspectives to one another, or nearly so. The colors are white or nearly white, flesh-red, bluish, or greenish.
    • In mineralogy, one of an extremely typical number of closely relevant nutrients, all silicates of aluminum, and either calcium, sodium, potassium, or perhaps in one instance barium.
    • any of several hard crystalline nutrients that contain aluminum silicates of potassium or sodium or calcium or barium
    • Any of a small grouping of abundant rock-forming minerals happening principally in igneous, plutonic, plus some metamorphic stones, and comprising silicates of aluminum with potassium, sodium, calcium, and, seldom, barium. About 60 % of the earth's exterior crust consists of feldspar.
    • Any of a large group of rock-forming nutrients that, collectively, form about 60per cent regarding the earth's exterior crust. The feldspars are aluminum silicates associated with alkali metals sodium, potassium, calcium and barium. Feldspars would be the major constituents of igneous and plutonic rocks.
    • A name given to several nutrients, closely associated in crystalline kind, and all silicates of alumina with either potash, soda, lime, or, in a single instance, baryta. They take place in crystals and crystalline masses, vitreous in luster, and breaking instead easily in 2 guidelines at correct sides to one another, or nearly therefore. The colors usually are white or nearly white, flesh-red, bluish, or greenish.
    • In mineralogy, certainly one of an extremely common set of closely associated nutrients, all silicates of aluminium, together with either calcium, salt, potassium, or perhaps in one instance barium.
    • any of a group of difficult crystalline minerals that contains aluminum silicates of potassium or sodium or calcium or barium
    • A name given to a team of nutrients, closely relevant in crystalline form, and all sorts of silicates of alumina with either potash, soft drink, lime, or, in a single case, baryta. They take place in crystals and crystalline masses, vitreous in luster, and breaking instead effortlessly in two instructions at right sides together, or nearly therefore. The colors are usually white or nearly white, flesh-red, bluish, or greenish.
    • In mineralogy, one of a rather typical number of closely relevant nutrients, all silicates of aluminum, with either calcium, sodium, potassium, or in one instance barium.
    • any of a group of hard crystalline nutrients that contain aluminum silicates of potassium or sodium or calcium or barium
