  • Anthophyllite: Mineral information, data and localities.

    www.mindat.org/min-254.html The anthophyllite group are orthorhombic amphiboles in the magnesium-iron-manganese amphibole subgroup. The minerals in this root name group may have either Pnma or Pnmn (proto- prefixed name) space-group symmetry. The anthophyllite group's composition is defined with A (Na+K+2Ca)

  • Mineral Gallery - The Inosilicate Subclass

    www.galleries.com/minerals/silicate/inosilic.htm The Inosilicates include two distinct groups: the single chain and double chain silicates. In the single chain. group the tetrahedrons share two oxygens with two other tetrahedrons and form a seemingly endless chain.. The ratio of silicon to oxygen is thus 1:3. The tetrahedrons alternate to the left and then to the right along the line formed by the linked oxygens although more complex chains ...

The X represents large ions such as sodium or potassium and this site can be left vacant. The Y can be populated by sodium, calcium, iron (+2), lithium, manganese (+2), aluminum and/or magnesium and more rarely zinc, nickel, or cobalt. The Z can be filled by ions such as Iron (+3), manganese ...

  • List of minerals (synonyms) - Wikipedia

    en.wikipedia.org/wiki/List_of_minerals_(synonyms) The International Mineralogical Association (IMA) is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.. This list contains mineral synonyms, varieties and polytypes.
