The comprehensive studies of rare-metal - rare-earth minerals of carbonatit associations were carried out. Some rarest mineral species were investigated. Two minerals were attested by the Commission on new minerals of International Mineralogical Association as new.

There are over 3,500 recognized mineral species and countless mineral varieties that have been classified as crystalline phases using the conventional methods listed above. Guidelines for naming minerals have been published by the Commission on New Minerals and Mineral Names (CNMMN) of the International Mineralogical Association (IMA).

The physiochemical environment of the earth has placed certain elements in common association and produced a variety of minerals. Minerals, classified according to a well-known and well-documented system based on the chemistry of the compounds, have been presented in several compendiums (e.g., Strunz, 1941 Palache, Berman and Frondel, 1944). Several glossaries aid in identifying minerals and cross-reference the more than 6000 names that have been used for the approximately 3000 known minerals (Embrey and Fuller, 1980 Fleischer, 1987). Each year about 100 new minerals are proposed to the International Mineralogical Association Commission on New Minerals and Mineral Names, of which about half are accepted as new species (Skinner and Skinner, 1980). 

Mineral A naturally occurring element or compound defined by its chemical composition and crystal structure (see chapter 2). By custom in recent times, mineral species have been given names ending in ite. Each year, about 100 new species are proposed, and usually about half are accepted by the International Mineralogical Association Commission on New Names as bona fide new species. The Glossary of Mineral Species (Fleischer, 1987) is a current source of information. Updates are published annually in the Mineralogical Record. 

Table 7 lists the currently known aluminosilicate zeolites based upon definition by their unique frameworks following Baerlocker, Baerlocher, Meier, and Olson. It also contains typical unit cell compositions, the lUPAC code, and type localities, but is restrictive in the sense that it does not consider the mineralogical aspects of the study of zeolites. The authoritative body for these is the Subcoimnittee for Zeolite NomenclaMe of the Conunission on New Minerals and Mineral Names of the International Mineralogical Association. Their guidelines have been cited in a recent book on natural zeolites by Tschemich, as follows. 

The name fassaite remains embedded in the literature even though the International Mineralogical Association (Morimoto et al., 1988) recommended—wrongly in this writer s opinion—dropping that name for this unique and important pyroxene variety in favor of subsilicic titanoan aluminian pyroxene. ... 

To prevent the continuing proliferation of superfluous mineral names by uncritical publication, the International Mineralogical Association (IMA) has created a Commission on New Minerals and Mineral Names which undertakes regular voting the chairman of this Commission, Dr. Michael Reischer, deserves our heartfelt gratitude for his admirable work. 

As a result, the number of minerals approved by the Commission on New Minerals Mineral Names of the IMA (International Mineralogical Association) has grown from about 2500 in 1978 to about 4000 at present, with about 60 to 80 new minerals added each year.

The natural zeolite community has followed a different path towards a systematisation of its nomenclature. An historically-determined nomenclature in which the crystal structure, the nature of the charge-compensating cation and some thermal properties were taken into account in a non-systematic manner [41] has been replaced by a nomenclature in accordance with the rules of the International Mineralogical Association (IMA) [42], in which both the structure and composition of the mineral are considered. This has led to a substantial increase... 

The concept of natural zeolite and the connected classification underwent numerous changes in the last seventy years. The first definition, taking care not only of the physical-chemical behaviour, but also of the peculiar structure, is due to Hey in the early 1930s [22]. Further proposals on this subject were made by Smith [23] and Liebau [24], but the discovery of new minerals having only partly the structural features, the chemistry and the properties of the "traditional" zeolites, made necessary the redefinition of the term "zeolite" and the proposition of novel nomenclature rules. A Committee was constituted for this in 1993 by the International Mineralogical Association. After a capillary work lasted about five years a Report was produced on the Recommended nomenclature for zeolite minerals [25]. 

In recent years a Mica Committee was appointed by the Commission on New Minerals and Mineral Names of the International Mineralogical Association. Its report (Rieder et. al. 1998) represents the standard reference for mica nomenclature. A synoptic table of the present species, with the derivation of their names, the localities of first occurrence, and references are in Appendix I. 

Marcopoulos and Economou foimd almost pure nickel hydroxide in the Vermion region of northern Greece, described it comprehensively, named it theophrastite [81MAR/ECO], and studied its genesis [83ECO/MAR]. The new mineral and its name were approved of by the Commission on New Minerals and Mineral Names, the International Mineralogy Association, IMA.

In the tables the data are presented in the following format the mineral name is given in the heading. A synonym, variety and/or discredited name, if any, is also given, in parentheses. A mineral name written in capital letters represents a well-described mineral or one approved by the Commission on New Minerals and Mineral Names of the International Mineralogical Association (IMA). A mineral name in lower case is a synonym, variety or discredited name. The chemical formula, and then the structural formula, are given below the mineral name. The chemical symbol Ln is used for La-Lu, and R stands for rare earths including yttrium. 

Column 1 presents the mineral name accoring to the International Mineralogical Association (IMA), moreover, its Chemical Abstract Registered Number in brackets [CAS RN], the synonym(s) (syn.), its etymology and the Powder Diffraction File (PDF) and in the Inorganic Crystal Structure Datafile (ICSD) are also indicated when available,...

The fundamental unit in the nomenclature recognized by the International Mineralogical Association is the mineral species. Each species has a unique name. Very strict criteria are applied for recognizing the right of a newly discovered mineral to be erected to species status. Existing names are occasionally revised as fresh data indicate some correction to the established nomenclature.
