TL;DR: The list of the most common and useful rock-forming minerals likely numbers in the several hundreds as discussed by the authors, and an expansion to the list initiated by Kretz (1983) was proposed by Spear.
Abstract: Nearly 30 years have elapsed since Kretz (1983) provided the mineralogical community with a systematized list of abbreviations for rock-forming minerals and mineral components. Its logic and simplicity have led to broad acceptance among authors and editors who were eager to adopt a widely recognized set of mineral symbols to save space in text, tables, and figures. Few of the nearly 5000 known mineral species occur in nature with a frequency sufficient to earn repeated mention in the geoscience literature and thus qualify for the designation “rock-forming mineral,” but a reasonable selection of the most common and useful rock-forming minerals likely numbers in the several hundreds. The original list by Kretz (1983) contained abbreviations for 193 of these. We propose an expansion to the list initiated by Kretz (1983) (see next page). Modest expansions and revisions were made by Spear …

TL;DR: In this article, the absolute energy positions of conduction and valence band edges were compiled for about 50 each semiconducting metal oxide and metal sulfide minerals, and the relationship between energy levels at mineral semiconductor-electrolyte interfaces and the activities of these minerals as a catalyst or photocatalyst in aqueous redox reactions were reviewed.
Abstract: The absolute energy positions of conduction and valence band edges were compiled for about 50 each semiconducting metal oxide and metal sulfide minerals. The relationships between energy levels at mineral semiconductor-electrolyte interfaces and the activities of these minerals as a catalyst or photocatalyst in aqueous redox reactions are reviewed. The compilation of band edge energies is based on experimental flatband potential data and complementary empirical calculations from electronegativities of constituent elements. Whereas most metal oxide semiconductors have valence band edges 1 to 3 eV below the H2O oxidation potential (relative to absolute vacuum scale), energies for conduction band edges are close to, or lower than, the H2O reduction potential. These oxide minerals are strong photo-oxidation catalysts in aqueous solutions, but are limited in their reducing power. Non-transition metal sulfides generally have higher conduction and valence band edge energies than metal oxides; therefore, valence band holes in non-transition metal sulfides are less oxidizing, but conduction band electrons are exceedingly reducing. Most transition-metal sulfides, however, are characterized by small band gaps (<1 eV) and band edges situated within or close to the H2O stability potentials. Hence, both the oxidizing power of the valence band holes and the reducing power of the conduction band electrons are lower than those of non-transition metal sulfides.

TL;DR: The Sous-Commission Pyroxenes creee par la Commission Nouveaux Mineraux et Noms de Mineraux (C.N.M.A) as discussed by the authors, who presente son rapport final sur la nomenclature des pyroxenes.
Abstract: La Sous-Commission Pyroxenes creee par la Commission Nouveaux Mineraux et Noms de Mineraux (C.N.M.M.N.) de l'Association Mineralogique Internationale (I.M.A.) presente son rapport final sur la nomenclature des pyroxenes. Les recommandations de la Sous-Commission proposees dans ce rapport ont ete officiellement acceptees par la Commission. Des noms acceptes et largement utilises ont ete definis chimiquement, combinant des methodes nouvelles et conventionnelles, de facon a etre en accord dans la mesure du possible avec l'usage actuel generalement admis. Vingt noms ont ete officiellement acceptes, parmi eux treize sont employes pour representer des poles purs de composition chimique bien determinee. Dans les solutions solides binaires ordinaires, les noms d'especes sont donnes par les termes extremes suivant la \"regle des 50%\". Des adjectifs modificatifs sont ajoutes aux noms des pyroxenes pour indiquer des quantites exceptionnelles de constituants chimiques. Ce rapport inclut une liste de 105 noms de pyroxene utilises precedemment, qui ont ete rejetes officiellement par la Commission.
