![]() Charoite from its type locality is famous for purple to violet coloration caused by traces of Mn 3+, whereas charoite from the Patynskiy massif is whitish-grey to brown. The main difference between the charoite varieties from the two localities is the color. Similar to the charoite from Murun, this one from the Patynskiy massif forms long-fibrous aggregates with vitreous to silky luster and has good cleavage in three directions. All these rocks are studied in detail and described in the geologic literature. ![]() While basic rocks are strongly dominant throughout the massif and show a concentric-zonal structure, other ones are spread out locally in central and south-western parts of the massif. Other types of rocks are represented by rare dikes of microgranites, selvsbergites, grorudites, veins of monticellite–melilite–nepheline rocks, acid and alkaline pegmatites, and alkaline syenites. It is composed mainly of basic rocks including different types of gabbro (olivine and titanomagnetite ones with coarse grained pegmatoid, vesicular, and porphyritic textures), as well as troctolites, norites, pyroxenites, anorthosites, etc. Patynskiy massif was formed in near-surface conditions and, most probably, represents a subvolcano. Its contacts fall from the periphery to the central part showing a funnel form of the massif. It occupies an approximate area of 50 km 2 and has an isometric outline. Geologically, Patynskiy massif belongs to an Early Devonian gabbro-syenite formation. Type material is deposited in the collections of the Fersman Mineralogical Museum of the Russian Academy of Sciences, Moscow, Russia with the registration number 5369/1. Patynite is an inosilicate with a new type of sextuple branched tubular chain ∞ with an internal channel and as the repeat unit. ![]() The crystal structure was solved by direct methods and refined to R 1 = 0.032. The empirical formula based on 23 O apfu is Na 1.00K 1.00Ca 4.02Si 8.99O 23. The Raman and IR spectra shows the absence in the mineral of H 2O, OH −, and CO 3 2− groups and B–O bonds. Its density measured by flotation in Clerici solution is 2.70(2) g/cm 3 density calculated from the empirical formula is 2.793 g/cm 3. It has vitreous to silky luster, white streaks, brittle tenacity, and stepped fractures. Patynite is colorless in individual lamellae to white and white-brownish in aggregates. ![]() Other associated minerals include monticellite, wollastonite, pectolite, calcite, and orthoclase. Patynite forms lamellae up to 1 × 0.5 cm and is closely intergrown with charoite, tokkoite, diopside, and graphite. (Patynskiy massif), Tashtagolskiy District, Kemerovo (Kemerovskaya) Oblast’, Southern Siberia, Russia. The new mineral patynite was discovered at the massif of Patyn Mt. ![]()
