In this work, we refine the crystal structure of childrenite. Additionally, we provide compositional data to substantially extend the published solid-solution series between childrenite and eosphorite, the Fe and Mn endmembers, respectively. We analyze the valence state of iron to avoid erroneous classification of ernstite or potential discovery of "oxychildrenite", a mineral species not yet confirmed to be stable in nature.

This work reports the full crystal-chemical characterization of gersdorffite from Contrada Zillì (Peloritani Mountains, Sicily, Italy). The structural type shown by gersdorffite (ordered polytype 213) and its chemistry agree with low-temperature crystallization conditions. Moreover, the chemical zoning of the studied crystals recorded changes in the crystallization physicochemical conditions. This zoning may be due to a multistage crystallization, related to the evolution of the ore deposits.

The plagionite group is a family of complex sulfides (
lead-antimony sulfosalts) encountered in various Pb-Cu-Zn ore deposits. Analysis of these crystal structures confirms a systematic Pb-versus-Sb substitution in two adjacent cation positions. Such a substitution varies according not only to the Pb / Sb ratio of each member but also, apparently, to the kinetics of crystallization. Re-examination of a Pb-free synthetic derivative permitted its redefinition as a Na-Sb sulfosalt.

The new mineral heimite was originally discovered on the mine dumps of the Grosses Chalttal deposit, Mürtschenalp district, Glarus, Switzerland. Its relatively simple chemistry is formed by water and ions of lead, copper, arsenic, hydrogen and oxygen. The mineral's crystal structure is related to the well-known duftite, which is also observed to grow on crystals of heimite. While heimite has so far only been found in the central Alps, it is expected to occur in other copper deposits worldwide.

The paper proposes an application called OxyEMG (Oxyspinel group End-Member Generator), which is an improved version of EMG. This tool allows for calculating the portions of 31 end-members of the oxyspinel group from data obtained with an electron microprobe. This is fundamental since this group of minerals is considered to be tectonic tracers; their integral composition should be taken into account and not only those end-members that make up the magnetite or ulvöspinel prisms.

There are unresolved problems related to the nomenclature and identification of mineral species belonging to the triphylite group of minerals. They can be solved by discarding the traditional views on succession of mineral species during oxidation. In other words, it is necessary to separate the concepts of the origin of the mineral and the boundaries of the species.

The paper gives a characterisation of the new mineral species, whiteite-(CaMnFe), which has recently been approved as a new mineral (proposal IMA2022-077). The study included a single-crystal structure refinement that, when combined with electron microprobe analyses, confirmed that the mineral was a new member of the whiteite subgroup of the jahnsite group of minerals. Relationships between the crystal structure and the unit-cell parameters for the whiteite-subgroup minerals are discussed.

It was determined that growth bands showing the straight birefringence in octahedral sectors and the enrichment of graphite inclusions in cuboid sectors of Zimbabwean mixed-habit diamonds may both be due to the fluctuation of temperature during crystallization, and they displayed positive anomalies of plastic deformation, residual stress, nitrogen concentration, and VN3H defects. This conclusion clearly revealed the correlation between birefringence and spectroscopic properties of diamonds.

Minerals have complex crystal structures, but many common minerals are built from the same chemical building blocks. TotBlocks is a novel, open-source tool for investigating these structures. It consists of 3D-printed modules representing the silica tetrahedra and metal–oxygen octahedra that form the shared chemical building blocks of rock-forming minerals. TotBlocks is a low-cost visualization tool that relates mineral properties (habit, cleavage, and symmetry) to crystal structures.

A new mineral has been discovered, an amphibole, with the name ferri-taramite, which has now been approved by the International Mineralogical Association. The paper discusses the significance of the discovery in relation to other amphiboles found worldwide. This taramite is unique in that it is from a skarn associated with ore and is not of magmatic origin. For the description we have used many methods, including X-ray diffraction, chemical analyses and several types of spectroscopy.

Ferro-ferri-holmquistite (IMA2022-020), ideal formula ☐Li2(Fe32+Fe23+)Si8O22(OH)2, was found in albitized granite from the Iwagi islet, Ehime, Japan. It is a Fe2+Fe3+ analogue of holmquistite and belongs to the lithium subgroup amphiboles. Ferro-ferri-holmquistite occurs as blue acicular crystals typically replacing the biotite and is the product of metasomatic mineral replacement reactions by dissolution–reprecipitation processes associated with Na- and Li-rich hydrothermal fluids.

This paper describes the characterisation of a new mineral from a South Australian phosphate quarry. The characterisation included chemical analyses, infrared spectroscopy, and a determination and refinement of the crystal structure. The results showed that the mineral has a unique crystal chemistry, but it is closely related to the well-known phosphate mineral crandallite.

The study of the original material of beraunite from the type locality Hrbek, Czech Rep., from collections of the TU Bergakademie Freiberg (Germany) and National Museum Prague (Czech Republic) proved the identity of the minerals beraunite and eleonorite. Because the name beraunite has priority, we consider the name eleonorite to be redundant and proposed to abolish it. The proposal 21-D approved by the IMA discredited eleonorite and accepted the formula of beraunite Fe3+6(PO4)4O(OH)4·6H2O.

A reinvestigation of angastonite from the type locality has shown that it is a mixture of crystalline phases and an amorphous phase, with the published formula corresponding to the amorphous phase. A redefinition proposal for angastonite as an amorphous mineral was approved by the IMA CNMNC. Our study showed how the amorphous phase formed and how it progressively recrystallises as new crandallite-related minerals.

Two new nanominerals: titanium monophosphide and titanium disilicide, formed at pressures of Earth’s upper mantle by the action of methane and hydrogen from the mantle on basaltic melts in the Luobusa ophiolite (Tibet). The minerals were characterized by 3D electron diffraction, which can solve the crystal structures of phases less than a micrometer in size. The results contribute to our understanding of deeply subducted crustal rocks and their exhumation back to the Earth's surface.

Wumuite, ideally KAl0.33W2.67O9 with a hexagonal tungsten bronze (HTB)-type structure, is another new mineral containing potassium and tungsten found in the Pan–Xi region in China after tewite was discovered.

Wumuite was speculated to be formed by a metasomatic reaction between W-rich hydrothermal fluids and the potassium feldspar in the monzonite.

Molybdates are of a great interest due to their ionic conductivity, negative thermal expansion, and immobilization of radionuclides. The new mineral tancaite-(Ce), FeCe(MoO4)3•3H2O, shows a new structure type never observed in natural and synthetic molybdates. Its cubic average structure may be described as a derivative of the perovskite structure, in which Fe-centred octahedra are linked through MoO4 groups. The ordering of Mo and O atoms results in one or more complex superstructures.

Type material for heliophyllite, preserved in the Swedish Museum of Natural History in Stockholm, was re-investigated through a combined EPMA (electron probe X-ray microanalysis), Raman, and X-ray powder diffraction (XRPD) and single-crystal study. EPMA chemical data, together with Raman and single-crystal structural studies, point to heliophyllite being identical to ecdemite. XRPD synchrotron data highlight the presence of a minor quantity of finely admixed finnemanite in the analyzed material.
