如在高温下碱性长石 中K和Na可以互呈类质同象替代而形成(K,Na)A1Si3O8或(Na,K)A1Si3〇s固溶体；但在低 温下则发生固溶体分离,而形成由钾长石KAl Si3O8和钠长石NaAl Si3Os两种矿物组成的条 纹长石。压力的增加往往会限制类质同象替代的范围,并促使固溶体分离。
The crystal structure and hydrogen positions of serandite, NaMn 2 [Si 3 O 8 (OH)], have been refined from single-crystal X-ray and time-of-flight neutron diffraction data at ambient conditions. The proton occupies an asymmetric, double-well position between O3 and O4, confirming one of the shortest asymmetric hydrogen bonds known in minerals with d(O3...O4) = 2.464(1) Å (X-ray) and 2.467(1 ...
