INCLUSIONS IN MINERALS AS THE OBJECTS OF CRYSTALLOGRAPHY
G. Kul’chyts’ka, D. Voznyak, D. Chernysh
The article introduces the development of inclusions in minerals study from a separate department of geological disciplines to an autonomous science. It is stressed that the study always were and continue to be a branch of crystallographic science. Only on such principles correct interpretation of inclusion data is possible. It is recommended to add diagenetic inclusions in the list of known genetic types of inclusions. Solid, liquid and gaseous inclusions arise up in minerals as a result of disintegration of isomorphic and admixture solid solutions. The last forms in the result of unequal capture of admixtures by the crystallizing mineral. Diagenetic inclusions enable to trace the fluid evolution inside crystals without an exchange with an external mineral-forming environment.
Key words: thermobarogeochemistry, exsolution diagenetic inclusions, disintegration of nonisomorphic solid solutions, crystallography.

The types and concentrations of paramagnetic centres in the zoned quartz crystal and others quartz crystals from pegmatites have been investigated. It is found that the concen-trations of the electron Å1?-centres and the hole O23–-centres represent the quartz crystalli-zation temperature, ðÍ and chemical composition of the mineral-forming fluid. Correla-tions between the concentrations of electron and hole centres in quartz crystal zones, which are different for ?- and ?-quartz, have been established. Key words: quartz, quartz generations, formation conditions, paramagnetic centres, electron paramagnetic resonance.

GENETIC TYPES OF FLUORITE FROM SYENITES OF YASTRUBETS’KYI MASSIF
(UKRAINIAN SHIELD)

Palladin av. 34, UA – 03680 Kyiv, Ukraine
E-mail: kulchec@igmr.relc.com
Inclusions in fluorite from Yastrubets’kyi massif syenites have been studied. The fluorite was selected from crushed samples, collected in one of the boreholes. Two types of fluorite were identified: one with mineral inclusions and the other – with gas-liquid inclusions. Mineral inclusions have the evidence of melt formation. Water solution inclu-sions, supersaturated with carbonate-ions, dominate among gas-liquid inclusions. Com-parison of inclusions in fluorite from Yastrubets’kyi intrusion with the ones from Azov intrusion (Ukrainian Shield) showed that the process of fluorite formation to a large ex-tent was identical. In both intrusions the composition of fluorine-containing fluids changed from silicate-fluoride melt, enriched with heavy elements (Zr, TR, Fe), to the salt melt (chloride-fluoride in Azov massif, carbonate-fluoride – in Yastrubets’kyi) and farther to water solutions supersaturated with salts. In comparison with Azov, Yas-trubets’kyi intrusion has been formed under conditions of higher fluid pressure and lower temperature. Carbonate components in the rock-forming fluid enable us to predict car-bonatite bodies with rare-earth mineralization within Yastrubets’kyi layering intrusion. Low-density gas inclusions, which indirectly prove the presence of hydrogen mole-cules in the mineral-forming fluid, were revealed.
Key words: syenite, fluorite, melt inclusions, gas-liquid inclusions, hydrogen inclu-sions, rare-earth mineralization, Ukrainian Shield.

INFLUENCE OF POST-SEDIMENTATION PROCESSES
ON THE FORMATION OF CARNALLITE IN THE HALOID DEPOSITS OF THE PRECARPATHIANS

E-mail: mineral@franko.lviv.ua
The results of geological, mineralogical, geochemical and experiment investigations gave the possibility to conclude that potassium-magnesium deposits of the Precarpathians underwent considerable changes during post-sedimentation period. Dehydration of crys-tallohydrates and formation of low water and dry minerals under the influence of the increasing temperature and pressure took place on the katagenesis stage. The brines were formed from the extracted water, and carnallite and the other minerals in the fault zones were formed from them.
Key words: carnallite, thermal-dynamic-metamorphism, transformation of crystallohydrates, fault zones, sources of salt brines, mineral formation, Precarpathians.

TWO DEBATABLE PROBLEMS REGARDING HYDROMICAS
Superfluous quantity of water in micas caused to name them hydromicas. Mineralo-gists described hydrobiotite in 1880, hydromuscovite in 1889 and hydrophlogopite in 1895. In 1937 R. Grim described hydromuscovite of Illinois sours named illite. Subcom-mittee of the Commission on New Minerals and Mineral Names proposes to exclude the name of hydromica and substitute it by illite. This conclusion contradicts common sense, priority and the rule of reflection of properties in the name of the mineral. Existence of oxonium in micaceous clay minerals have been demonstrated 30–40 years ago by infrared absorption, proton magnetic resonance, tritium exchange data and by the method of comparison of calculated and experimental data. At present this conclu-sion is confirmed by methods of radiospectroscopie and neutron diffraction. However certain mineralogists continue neglecting the presence of oxonium in hydromica. This puts the break on the development of mineralogy.
Key words: hydromica, oxonium, illite, mineralogy.
