“…Ilmajokite, Na 11 KBaCe 2 Ti 12 Si 37.5 O 94 (OH) 30 •29H 2 O, is the third most complex mineral, which was first reported from the hydrothermal vein in Karnasurt Mountain, Lovozero, Kola Peninsula, Russia (Bussen et al 1972). The mineral easily dehydrates in air, which prevented its structure solution for more than forty-five years.…”

Through the years, mineralogical studies have produced a tremendous amount of data on the atomic arrangement and mineral properties. Quite often, structural analysis has led to elucidate the role played by minor components, giving interesting insights into the physicochemical conditions of minerals and allowing the description of unpredictable structures that represented a body of knowledge critical for assessing their technological potentialities. Using such a rich database, containing many basic acquisitions, further steps became appropriate and possible, into the directions of more advanced knowledge frontiers. Some of these frontiers assume the name of modularity, complexity, aperiodicity, and matter organization at not conventional levels, and will be discussed in this review.

“…The vanarsite-group minerals form from low-temperature aqueous solutions with V and As derived from the oxidation of primary unoxidised phases. Zolotarev et al (2020) reported the crystal structure of ilmajokite, Na 11 KBaCe 2 [Ti 12 Si 37.5 O 94 (OH) 31 ]•29H 2 O, the third most complex mineral, which was first reported from a hydrothermal vein in Karnasurt Mountain, Lovozero, Kola Peninsula, Russia (Bussen et al, 1972). The crystal structure is based on a 3D titanosilicate framework consisting of trigonal prismatic titanosilicate…”

The complexities of chemical composition and crystal structure are fundamental characteristics of minerals that have high relevance to the understanding of their stability, occurrence and evolution. This review summarises recent developments in the field of mineral complexity and outlines possible directions for its future elaboration. The database of structural and chemical complexity parameters of minerals is updated by H-correction of structures with unknown H positions and the inclusion of new data. The revised average complexity values (arithmetic means) for all minerals are 3.54(2) bits/atom and 345(10) bits/cell (based upon 4443 structure reports). The distributions of atomic information amounts, chemIG and strIG, versus the number of mineral species fit the normal modes, whereas the distributions of total complexities, chemIG,total and strIG,total, along with numbers of atoms per formula and per unit cell are log normal. The three most complex mineral species known today are ewingite, morrisonite and ilmajokite, all either discovered or structurally characterised within the last five years. The most important complexity-generating mechanisms in minerals are: (1) the presence of isolated large clusters; (2) the presence of large clusters linked together to form three-dimensional frameworks; (3) formation of complex three-dimensional modular frameworks; (4) formation of complex modular layers; (5) high hydration state in salts with complex heteropolyhedral units; and (6) formation of ordered superstructures of relatively simple structure types. The relations between symmetry and complexity are considered. The analysis of temporal dynamics of mineralogical discoveries since 1875 with the step of 25 years show the increasing chemical and structural complexities of human knowledge of the mineral kingdom in the history of mineralogy. In the Earth's history, both diversity and complexity of minerals experience dramatic increases associated with the formation of Earth's continental crust, initiation of plate tectonics and the Great Oxidation event.

“…The Selsurt mountain located in the north-eastern part of the well-known huge Lovozero alkaline complex, Kola Peninsula, Russia is composed mainly of rocks in a layered complex of urtites, foyaites and lujavrites (Bussen and Sakharov, 1972). Various metasomatic assemblages occur at the contacts of the igneous alkaline rocks with metamorphic rocks on the northern spur of the Selsurt mountain.…”

The new eudialyte-group mineral selsurtite, ideally (H 3 O) 12 Na 3 (Ca 3 Mn 3 )(Na 2 Fe)Zr 3 Si[Si 24 O 69 (OH) 3 ](OH)Cl•H 2 O, was discovered in metasomatic peralkaline rock from the Flora mountain, the northern spur of the Selsurt mountain, Lovozero alkaline massif, Kola Peninsula, Russia. The associated minerals are aegirine, albite and orthoclase, as well as accessory lorenzenite, calciomurmanite, natrolite, lamprophyllite, and sergevanite. Selsurtite occurs as brownish-red to reddish-orange, equant or flattened on (0001) crystals up to 2 mm across and elongate crystals up to 3 cm long. The main crystal forms are {0001}, {11-20}, and {10-11}. Selsurtite is brittle, with the Mohs' hardness of 5. No cleavage is observed. Parting is distinct on (001). D(meas) = 2.73(2), D(calc) = 2.722 g•cm -3 . Selsurtite is optically uniaxial, negative, with  = 1.598(2) and  = 1.595(2). The chemical composition is (wt.%, electron
