calcite

noun

mass noun
  • A white or colourless mineral consisting of calcium carbonate. It is a major constituent of sedimentary rocks such as limestone and is deposited in caves to form stalactites and stalagmites.

    • ‘The nonzeolites apophyllite, calcite, and quartz commonly occur at many localities.’
    • ‘Matrix minerals of the septaria are ferroan dolomite, quartz, calcite, and pyrite.’
    • ‘This cavity may then be filled with coal, calcite, siderite, or any other form of sediment.’
    • ‘The calcite formed scalenohedral and rhombohedral crystals on some of the quartz crystal groups.’
    • ‘Specimens of this unusual calcite are on display at the Mineral Museum.’
    • ‘Around one corner, the mine became snow white with calcite and sodium chloride.’
    • ‘The calcite and other such minerals suffered greatly from exposure to the weather.’
    • ‘Experimental data ranges for both quartz and calcite rocks are indicated along the stress axis.’
    • ‘Quartz is the dominant mineral in veins in siliceous rocks, calcite in limestones, and gypsum in gypsiferous sediments.’
    • ‘The major mineral constituents of coal balls are calcite, dolomite, ferroan dolomite and pyrite.’
    • ‘The sparry calcite is interpreted as a single phase of precipitation that infilled external moulds of the arthropod.’
    • ‘The walls of the cave were clean white limestone and decorated with pretty cave flowers and calcite crystals.’
    • ‘The limestone is highly fractured and contains abundant calcite and quartz veins.’
    • ‘Strontium concentrations in seawater reflect the diagenesis of Sr-rich aragonite to calcite on continental shelves.’
    • ‘Zeolite veins appear to be later than prehnite veins, and calcite is the last mineral to form veins in the dyke samples.’
    • ‘The trick to recovering fine specimens is to collect the chunks of rock showing prehnite and calcite.’
    • ‘Abundant thin calcite and quartz veins cut the schists, and have been boudinaged and rotated parallel to the first cleavage.’
    • ‘The main gangue minerals that make up the vein are massive white calcite, quartz, and prehnite.’
    • ‘In some geodes, the brown calcite is completely hidden by clear calcite secondary growth.’
    • ‘Phosphate may also replace calcite or be precipitated instead of calcite in neutral or slightly acidic pH conditions.’
    • ‘Further up the core into the Waulsortian sequence, the limestones are cleaner and the breccia clasts are cemented by calcite.’
    • ‘Analcime may also be associated with quartz crystals, calcite, and common opal.’
    • ‘Other than clay minerals, calcite and pyrite are the most common secondary minerals present.’
