THE IMA–CNMNC DOMINANT-CONSTITUENT RULE REVISITED AND EXTENDED
mineral nomenclature solid-solution series dominant-constituent rule dominant-valency rule IMA–CNMNC
2013/12/6
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...
Nomenclature of the apatite supergroup minerals
nomenclature apatite supergroup apatite group hedyphane group belovite group britholite group ellestadite group
2013/12/6
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...
THE PYROCHLORE SUPERGROUP OF MINERALS: NOMENCLATURE
pyrochlore supergroup nomenclature pyrochlore group microlite group betafite group rom閕te group elsmoreite group
2013/12/6
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...
Nomenclature of the tourmaline-supergroup minerals
Tourmaline mineral chemistry nomenclature substitutions order-disorder
2013/12/6
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...
Nomenclature of the hydrotalcite supergroup;natural layered double hydroxides
LDH layered double hydroxide hydrotalcite hydrotalcite supergroup brucite nomenclature manasseite sjo¨grenite barbertonite cyanophyllite fouge`rite treⅴbeurdenite.
2013/12/6
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...
Alunite supergroup: recommended nomenclature
nomenclature alunite natroalunite kintoreite beaverite orpheite minamiite
2013/12/6
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...

IMA-CNMNC new guidelines, prefixes suffixes mineral nomenclature historical mineral names
2013/12/6
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...
Nomenclature of the garnet supergroup

2013/12/6
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...
