Summary
This issue contains description of rare pyrope-majorite garnet found in kersantite and spessartite dykes of Chetlas Kamen’,
Central Timan, Te-bearing fahlores and similar phases from various deposits and phases with composition similar to fahlores,
enargite, and luzonite from deposits of Bulgaria; problems concerning recalculation of chemical analyses of these minerals
are discussed. Carbonaceous matter and its mineral assemblages in pegmatites of various formations, mineralogical features
of multimetal deposits of Russia, Central Asia, and Kazakhstan are reported; role of sorbent minerals for concentration of
metals in the supergene zone of these deposits are discussed. Results of experimental study of species of Au, Ag, and
Pt-Pd-Sn intermetallic compounds at crystallization of Cu-Fe sulfide melt are given.
Part “Mineralogical Museums and Collections” introduces a collection of mosaic arts from funds of Fersman Mineralogical
Museum. In “Mineralogical Notes”, a problem of horizontal isomorphic substitutions of chemical elements is discussed. Part
“Discussion” contains paper, which continues essay on fundamental and genetic mineralogy published in previous issue and
uses the eudialyte group minerals to illustrate a problem of typomorphic features of minerals.
This issue is of interest to mineralogists, geochemists, geologists, researchers of Natural History museums, collectors and
amateurs of stone.

Garnet of the Pyrope-Majorite Series from Lamprophyres of Central Timan, p. 5 - 10
In kersantite and spessartite dikes of Chetlas Kamen’ among accessory garnets, that are rather rare in lamprophyres, there was discovered few and for the first time high-majorite pyrope garnet with majorite minal Mg3Fe2[SiO4]3 (26–42%), similar to majorite garnet originating from a meteorite. Majorite discovered in Coorara meteorite (Mason et al., 1968; Smith, Mason, 1970) is very rare in the terrestrial rocks. It is shown, that highmajorite pyrope to variable degree is associated with diamond. On the one hand, it occurs as inclusions in diamond crystals, on the other hand, in rocks, where such garnet is found, microcrystalline diamond is established . Pyropemajorite garnet in lamprophyres testifies to superdeep origin of lamprophyre magma. читать далее...

Carbonaceous Matters in Pegmatites of Different Genetic Types and their Role in Formation of Mineral Associations, p. 11 - 23
Comparative investigation of carbonaceous matters from pegmatites of different formations has been performed. These formations are as follows: high alkaline (Khibina and Lovozero massifs, Kola Peninsula), rare metal granitic (Viitaniemi, Finland), granitic of mica type (Northern Karelia), and alkaline granite amazonitic (Western Keyvy, Kola Peninsula). The existence of steady genetic relation between reduced forms of carbon and several characteristic incoherent rare “bitumenphilic” elements (U, Th, REE, Zr, Hf, Nb, Ta, W, Sn) and titanium has been shown as well. Possible mechanisms of the formation and the transformation of carbonaceous matters in pegmatites of different genetic types, their structure and role in processes of mineral genesis are discussed. читать далее...

Some Peculiarities of Mineralogy of the Deposits of Central Part of Structural-Metallogenic Zone Sredna-Gora, Bulgaria, p. 24 - 33
Results of investigation of samples from the Chelopech deposit are compared with literature data. Minerals are discovered which have very similar optical features and elemental composition to fahlore, enargite and luzonite. However, their formulae are not electroneutral by calculation per 29 atoms in the unit cell or per the fahlore formula. They become electroneutral only by recalculation per larger numbers of atoms in the unit cell (32, 33 and 34 atoms). It is assumed that these are new mineral species similar in optical properties and chemical composition to fahlore, enargite and luzonite. They have following idealized formulae: Cu+11Ме2+3(Te4+,ПМе3+)4S16, Cu+11Ме2+2Ме3+ПМе3+4S15, Cu+10Me2+3(Te4+,ПMe3+)4S16, Cu+8Cu2+2Fe2+3As4S15, Cu+8Cu2+3Fe2+2As4S15, Cu+2Cu2+3As2S7 (Me is the metals, ПMe is the semimetals). Goldfieldite and Te-tetrahedrite containing more than 24 wt.% tellurium are commonly heterogenous. They contain very small segregations of native tellurium. Moreover, tellurium may enter the sulfur position in their structure. читать далее...
