  2. Mineral water - Wikipedia

    en.wikipedia.org/wiki/Mineral_water

    Mineral water is water from a mineral spring that contains various minerals, such as salts and sulfur compounds. It is usually still, but may be sparkling ( carbonated / effervescent ). Traditionally, mineral waters were used or consumed at their spring sources, often referred to as "taking the waters" or "taking the cure," at places such as ...

  3. Vitrinite - Wikipedia

    en.wikipedia.org/wiki/Vitrinite

    The study of vitrinite reflectance (or VR) is a key method for identifying the maximum temperature history of sediments in sedimentary basins.The reflectance of vitrinite was first studied by coal explorationists attempting to diagnose the thermal maturity, or rank, of coal beds.

  4. Mineral spring - Wikipedia

    en.wikipedia.org/wiki/Mineral_spring

    A chalybeate (iron-laden) mineral spring at Breznik, Bulgaria Tap tapan spring in Azarshahr, Iran. Mineral springs are naturally occurring springs that produce hard water, water that contains dissolved minerals. Salts, sulfur compounds, and gases are among the substances that can be dissolved in the spring water during its passage underground.

  5. Hot spring - Wikipedia

    en.wikipedia.org/wiki/Hot_spring

    Grand Prismatic Spring and Midway Geyser Basin in Yellowstone National Park. A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth.

  6. Deep ocean minerals - Wikipedia

    en.wikipedia.org/wiki/Deep_Ocean_Minerals

    DOW is present at depths of between 250 and 1500 meters. This deep ocean current moves very slowly under the influence of density and temperature gradients. The high mineral density is attributed to the depth-related pressure and the change in temperature from 20°C+ at the surface to 8°C at 600 meters depth generates the movement of this layer.

  7. Analcime - Wikipedia

    en.wikipedia.org/wiki/Analcime

    Analcime (/ ə ˈ n æ l s iː m,-s aɪ m /; from Ancient Greek ἀνάλκιμος (análkimos) 'not strong') or analcite is a white, gray, or colorless tectosilicate mineral. Analcime consists of hydrated sodium aluminium silicate in cubic crystalline form. Its chemical formula is NaAlSi 2 O 6 · H 2 O.

  8. Fluid inclusion - Wikipedia

    en.wikipedia.org/wiki/Fluid_inclusion

    The methods of using fluid inclusions to identify mineral deposits include assessing the abundance of a specific inclusion type, looking into variations in the inclusions' temperatures of phase changes during heating and cooling, [2] and variations in other properties such as decrepitation behavior, and inclusions chemistry. [1]

  9. Mineral - Wikipedia

    en.wikipedia.org/wiki/Mineral

    Mineral classification schemes and their definitions are evolving to match recent advances in mineral science. Recent changes have included the addition of an organic class, in both the new Dana and the Strunz classification schemes. [152] [153] The organic class includes a very rare group of minerals with hydrocarbons. The IMA Commission on ...
