Mineralogical nomenclature in solid-solution series follows a system that has been called the 50% rule, more correctly the 100%/n rule or the dominant-constituent rule, in which the constituents are a...
The apatite supergroup includes minerals with a generic chemical formula IXM12 VIIM23(IVTO4)3X (Z  2); chemically they can be phosphates, arsenates, vanadates, silicates, and sulphates. Themaximum sp...
A new scheme of nomenclature for the pyrochlore supergroup, approved by the CNMNC朓MA, is based on the ions at the A, B and Y sites. What has been referred to until now as the pyrochlore group should b...
A nomenclature for tourmaline-supergroup minerals is based on chemical systematics using the generalized tourmaline structural formula: XY3Z6(T6O18)(BO3)3V3W, where the most common ions(or vacancy) at...
Layered double hydroxide (LDH) compounds are characterized by structures in which layers with a brucite-like structure carry a net positive charge, usually due to the partial substitution of trivalent...
Minamiite has been discredited and renamed natroalunite-2c to show a double unit-cell structure and natroalunite can be designated as natroalunite-1c to show a single unit-cell structure. Kintoreite c...
A new classification and nomenclature scheme for the amphibole-supergroup minerals is described, based on the general formula AB2C5T8O22W2, where A = o, Na, K, Ca, Pb, Li; B = Na, Ca, Mn2+, Fe2+, Mg, ...
After careful consideration of the semantics of status categories for mineral species names, minor corrections and disambiguations are presented for a recent report on the nomenclature of the pyrochlo...
New CNMNC guidelines are established, in order to standardize the use of prefixes and suffixes in mineral nomenclature,and to preserve historical names. The recommendations for the use of suffixes are...
The garnet supergroup includes all minerals isostructural with garnet regardless of what elements occupy the four atomic sites, i.e., the supergroup includes several chemical classes. There are presen...
Heretofore the nomenclature of axinites was very simple: the only name accepted by everybody was "axinite" itself, sometimes associated with the adjective "manganous". Since most, if not all, axinites...
Revisions to an earlier paper on the nomenclature of rare-earth mineral species are reported. Now, only the dominant element in a specified crystal-structure site within isostructural minerals may be ...
Numerous rare earth element analogues have been founcl for well-establishecl rareearth minerals. In order to prevent a multitude of impractical names, a system of nomenclature is proposed. A group nam...
月球陨石MIL05035岩石类型上属于普通辉石低钛玄武岩,粗粒辉长结构,无角砾化.主要矿物为辉石(60.2%)、斜长石(27.3%)和橄榄石(6.05%),次要矿物为石英(4.36%)、钛铁矿(1.25%)和陨硫铁(0.84%),含极少量富Ti、Fe尖晶石和磷灰石,广泛发育由钙铁辉石+铁橄榄石+石英组成的后成合晶三相集合体.辉石颗粒具有明显的化学成分不均匀性和出溶片晶,核部相对贫铁钙富镁(Fs30...
