This article reports about the Special Issue of the journal Minerals, which includes 13 articles on eudialyte crystal chemistry, mineralogy, and petrography. Moreover, recently the eudialyte group has been completed by a new mineral, the 31st member, selsurtite. Very substantial reports consider the eudialyte synthesis and new methods of mineral decomposition for extraction of some useful elements from its structure.</p></abstract><trans-abstract xml:lang="ru"><p>Один из самых сложных по составу и структуре минерал — цирконосиликат эвдиалит — открыт 200 лет назад, но его изучение продолжается до сих пор. В данной статье рассказывается о выходе специального выпуска журнала «Minerals», который содержит 13 статей по кристаллохимии, минералогии и петрографии эвдиалитов. Кроме того, недавно группа эвдиалита пополнилась новым, 31-м по счету минералом — селсуртитом, и очень важные сообщения касаются синтеза эвдиалита и нового способа разложения минерала для экстракции полезных элементов из его структуры.</p></trans-abstract><kwd-group xml:lang="en"><kwd>eudialyte</kwd><kwd>new mineral selsurtite</kwd><kwd>synthesis of eudialyte</kwd><kwd>mineral decomposition</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эвдиалит</kwd><kwd>новый минерал</kwd><kwd>селсуртит</kwd><kwd>синтез эвдиалита</kwd><kwd>разложение минерала</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Расцветаева Р.К., Чуканов Н.В., Аксенов С.М.
