  • Mineral - Wikipedia

    OverviewDefinitionChemistryPhysical propertiesClassificationAstrobiologySee alsoGeneral references

    A mineral is, broadly speaking, a solid chemical compound that occurs naturally in pure form. Minerals are most commonly associated with rocks due to the presence of minerals within rocks. These rocks may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct phases. Compounds that occur only in living beings are usually excluded, but some minerals are often biogenic (such as calcite) or are organic compoundsin the sense of chemistry (s

    Two- and Three-Component SystemsSystems with More Than Three Components Chemographic ProjectionsCompositions, Components, and ProjectionsTwo Component TransformationOther Teaching ResourcesTwo-component chemical systems can be plotted as compositions on a line. Three-component systems can be plotted on triangular diagrams. Traditionally, the ends of the line (or the corners of the triangle) are the components being considered, and dots show where different compositions plot. For example, we can plot phases in the system Fe-O on a line. Then we can \"pick off\" possible reactions. Any two phases (for example wust在serc.carleton.edu上查看更多信息
