Summary
Articles of the volume give a new data on komarovite series minerals, jarandolite, kalsilite from Khibiny massif, presents
a description of a new occurrence of nikelalumite, followed by articles on gemnetic mineralogy of lamprophyllite-barytolamprophyllite series minerals from IujaVritemalignite complex of burbankite group and mineral composition
of rare-metal-uranium, berrillium with emerald deposits in Kuu granite massif of Central Kazakhstan.
Another group of article dwells on crystal chemistry and chemical properties of minerals: stacking disorder of zinc
sulfide crystals from Black Smoker chimneys, silver forms in galena from Dalnegorsk, tetragonal Cu21S in recent
hydrothermal ores of Mid-Atlantic Ridge, ontogeny of spiralsplit pyrite crystals from Kursk magnetic Anomaly.
Museum collection section of the volume consist of articles devoted to Faberge lapidary and nephrite caved sculptures
from Fersman Mineralogical Museum.
The volume is of interest for mineralogists, geochemists, geologists, and to museum curators, collectors and amateurs
of minerals.
