Minerals minerals and their chemical compositions

  • Chemical Properties of Minerals - The Mineral and Gemstone ...

    For example, the hydrous mineral Opal has a loosely defined composition with an inconsistent amount of water in its structure, thus its chemical formula is written as "SiO 2 · nH 2 O". Some minerals, such as Torbernite, have a varying amount of water within fixed limits. The chemical formula for Torbernite is "Cu(UO 2)(PO 4) 2 · 12H 2 O".

  • Mineral - Simple English Wikipedia, the free encyclopedia

    Minerals are formed by natural processes. A few substances with the same chemical composition as minerals can be produced by living creatures as part of their shells or bones. The shells of molluscs are composed of either calcite or aragonite, or both. Traditionally, chemicals produced by living things are not considered minerals.

  • List of minerals (complete) - Wikipedia

    Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species. Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety.

  • Chemical Composition

    Additional information provided is the chemical composition expressed as the % oxide of the element. These data are provided to help in the comparison of mineral analyses which use oxide percent. The convention of reporting the oxide percent dates back to when minerals and rocks were analyzed using wet-chemical methods to precipitate an element.
