• Tschermakite - Wikipedia

    en.wikipedia.org/wiki/Tschermakite The endmember hornblende tschermakite (☐Ca 2 (Mg 3 Al 2)(Si 6 Al 2)O 22 (OH) 2) is a calcium rich monoclinic amphibole mineral. It is frequently synthesized along with its ternary solid solution series members tremolite and cummingtonite so that the thermodynamic properties of its assemblage can be applied to solving other solid solution series from a variety of amphibole minerals.

    www.mindat.org/min-4035.html Tschermakite is defined as a Tschermakite Group member with Mg>Fe2+ and Al>Fe3+ in the C position. Tschermakite has been redefined in the 2012 Amphibole nomenclature in that: 1) The formula is changed from ☐(Ca 2)(Mg 3 AlFe 3+)(Al 2 Si 6 O 22)(OH) 2 to ☐(Ca 2)(Mg 3 Al 2)(Al 2 Si 6 O 22)(OH) 2.

    www.classicgems.net/gem_tschermakite.htm Tschermakite is a fairly common but rarely identified mineral. It often occurs in association with massive green Zoisite and Ruby at the Mundarara Mine, Longido, Mt. Kilimanjaro, Kilimanjaro Region of Tanzania. Black inclusions of Tschermakite are frequently seen in attractive cabochons of bright green Zoisite and pinkish-red Ruby.
