Nomenclature of Pyroxenes

  • N. Morimoto
Article

Summary

This is the final report on the nomenclature of pyroxenes by the Subcommittee on Pyroxenes established by the Commission on New Minerals and Mineral Names of the International Mineralogical Association. The recommendations of the Subcommittee as put forward in this report have been formally accepted by the Commission. Accepted and widely used names have been chemically defined, by combining new and conventional methods, to agree as far as possible with the consensus of present use. Twenty names are formally accepted, among which thirteen are used to represent the end-members of definite chemical compositions. In common binary solid-solution series, species names are given to the two end-members by the “50% rule”. Adjectival modifiers for pyroxene mineral names are defined to indicate unusual amounts of chemical constituents. This report includes a list of 105 previously used pyroxene names that have been formally discarded by the Commission.

Die Nomenklatur von Pyroxenen

Zusammenfassung

Diese Arbeit über die Nomenklatur der Pyroxene ist der Endbericht eines Unterkomitees der Commission on New Minerals und Mineral Names der International Mineralogical Association. Die in dieser Arbeit vorgelegten Empfehlungen des Unterkomitees wurden von der Kommission angenommen. Akzeptierte und häufig verwendete Namen wurden unter Verwendung neuer und konventioneller Methoden und unter möglichst großer Übereinstimmung mit dem derzeitigen Gebrauch chemisch definiert. Zwanzig Namen wurden als bindend angenommen, von denen dreizehn Endglieder mit chemisch genau definierten Zusammensetzungen sind. Für gewöhnlich wurden die Namen von zwei Endgliedern einer binären Mischkristallreihe durch Anwendung der “50% Regel” ermittelt. Zur Darstellung ungewöhnlicher chemischer Zusammensetzungen wurden den Pyroxennamen ergänzende Eigenschaftswörter beigefügt. 105 ursprünglich verwendete Namen von Pyroxenen wurden bereits früher von der Kommission ausgesondert und sind in diesem Bericht aufgelistet.
