  2. Halite - Wikipedia

    en.wikipedia.org/wiki/Halite

    Halite dominantly occurs within sedimentary rocks where it has formed from the evaporation of seawater or salty lake water. Vast beds of sedimentary evaporite minerals, including halite, can result from the drying up of enclosed lakes and restricted seas.

  3. Hydrohalite - Wikipedia

    en.wikipedia.org/wiki/Hydrohalite

    Hydrohalite is a mineral that occurs in saturated halite brines at cold temperatures (below 0.1 °C). It was first described in 1847 in Dürrnberg, Austria. It exists in cold weather. Phase diagram of water–NaCl mixture. Hydrohalite has a high nucleation energy, and solutions will normally need to be supercooled for crystals to form

  4. Sodium chloride - Wikipedia

    en.wikipedia.org/wiki/Sodium_chloride

    It is transparent or translucent, brittle, hygroscopic, and occurs as the mineral halite. In its edible form, it is commonly used as a condiment and food preservative . Large quantities of sodium chloride are used in many industrial processes, and it is a major source of sodium and chlorine compounds used as feedstocks for further chemical ...

  5. Mineral - Wikipedia

    It can be measured as the quotient of the mass of the sample and difference between the weight of the sample in air and its corresponding weight in water. Among most minerals, this property is not diagnostic. Rock forming minerals – typically silicates or occasionally carbonates – have a specific gravity of 2.5–3.5. [88]

  6. Salt - Wikipedia

    en.wikipedia.org/wiki/Salt

    From cold solutions, salt crystallises as the dihydrate NaCl·2H 2 O. Solutions of sodium chloride have very different properties from those of pure water; the freezing point is −21.12 °C (−6.02 °F) for 23.31 wt% of salt, and the boiling point of saturated salt solution is around 108.7 °C (227.7 °F).

  7. Anhydrite - Wikipedia

    en.wikipedia.org/wiki/Anhydrite

    Anhydrite is 1–3% of the minerals in salt domes and is generally left as a cap at the top of the salt when the halite is removed by pore waters. The typical cap rock is a salt, topped by a layer of anhydrite, topped by patches of gypsum, topped by a layer of calcite. [ 8 ]

  8. The presence of water, minerals, salts and amino acids suggests it was possible for the building blocks of life to come together in interesting ways on Bennu, but Glavin said more research is ...

  9. Polyhalite - Wikipedia

    en.wikipedia.org/wiki/Polyhalite

    It has a Mohs hardness of 3.5 and a specific gravity of 2.8. It is used as a fertilizer. Polyhalite was first described in 1818 for specimens from its type locality in Salzburg, Austria. [2] It occurs in sedimentary marine evaporites and is a major potassium ore mineral in the Carlsbad deposits of New Mexico.
