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.read more

Quantitative analysis of trace OH in garnet and pyroxenes
TL;DR: In this paper, the integral specific absorption coefficients of 1.39 ± 0.14 (lσ), 7.09======± 0.32, and 15.6 ± 0.94 /(ppm H_2O) for pyrope, augite, and enstatite were determined by manometry after heating the samples and extracting H 2 gas under vacuum.

Mineralogical and chemical modification of components in CV3 chondrites: Nebular or asteroidal processing?
TL;DR: In this article, the authors investigated the relationship between alteration processes in carbonaceous carbonaceous chondrites and their origins in the nebular and asteroidal models for their origins and found that they were closely related in time and space.

Nomenclature of amphiboles
TL;DR: The Na-Ca-Mg-Fe-Mn-Li amphibole group was proposed in this article, which is defined by 0.50 apfu (atoms per formula unit), with members whittakerite and ottoliniite.

Omphacite in Californian metamorphic rocks
TL;DR: Omphacite is a common mineral in greenstones, metasediments and related Franciscan rocks of the glaucophane schist facies as discussed by the authors, and it also occurs in late veins cutting amphibolites, glaucaphane schists, eclogites, greenstones and occasionally metagraywackes.

TL;DR: This article presented nomenclature recommendations resulting from a six-year study of problems common to the disciplines of mineralogy and crystallography, including definitions of polytypism, topotaxy, syntaxy, and epitaxy, certain criteria for mineral names, preferred format for chemical formulae, and preferred symbols for crystallographic axes and repeat distances.
