The Snezhnoe phenakite-beryl deposit is one of the highest-grade deposits in the Altai-Sayan beryllium province. This deposit is spatially associated with the alkali granite of the Ognit Complex and localized in the apical part of the granitic pluton

A reliable criterion of quartz genesis is proved to be ratios of the concentrations of structural defects in this mineral, which are a function of its structural dynamic state. Within the scope of the theory of sparring defects, theoretical dependenc

K ( Al )[ Al 2 Si 2 O 10 ]( OH ) 2 isomorphous series. The micas of zinnwaldite composition contain 3–4% Li 2 O, and protolithionites have higher Fe and lower Li 2 O (1–3%) contents. These minerals typically occur in rare-metal granites, granite

The paper proposes pioneering data on the polarized optical absorption spectra of Li-Fe micas: intermediate members of the siderophyllite-zinnwaldite-polylithionite and annite-protolithionite-zinnwaldite-trilithionite series with variable Fe and Li p

Biotites are widespread trioctahedral Mg‐Fe micas that are intermediate members of the phlogopite‐annite join. Pure annite K [ Si 3 AlO 10 ]( OH ) 2 is known only as a synthetic compound; natural annites typically contain no more than 2.0‐2.5 f

A thermochemical study of natural lithium micas, iron-containing polylithionite and lepidolite, was performed on a high-temperature heat-flux Calvet microcalorimeter (Setaram, France). Melt solution calorimetry was used to measure the enthalpies of m
