Abstract

New data on the chemical composition and structure of minerals of the eudialyte group are reviewed with respect to their classification; structural prerequisites of their properties; and structural changes occurring upon isomorphous substitutions, decationization, hydration, and solid-phase transformations of eudialyte due to the processes of potassium metasomatism. The problems associated with the separation of mineral species are considered within the structural-chemical approach. The nomenclature of mineral species, their typomorphism, and a number of other problems important for modern mineralogy are discussed.
