Yk. Egorovtismenko, ON THE SEIDOZERITE-NACAPHITE POLYSOMATIC SERIES OF MINERALS - TITANIUM SILICATE ANALOGS OF MICA, Crystallography reports, 43(2), 1998, pp. 271-277
On the basis of a detailed crystal-chemical analysis, a seidozerite-na
caphite polysomatic series is constructed. The series includes eight m
inerals: seidozerite, lomonosovite, beta-lomonosovite, vuonnemite, qua
druphite, sobolevite, polyphite, and nacaphite. The polysomes consist
of seidozerite and/or nacaphite blocks in different proportions.
