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 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.

Liguowuite, a new member of the non-stoichiometric perovskite group minerals, ideally WO3, has been found in the Panzhihua–Xichang region, China. Liguowuite is monoclinic and is in space group P21 / n, with a = 7.32582(18) Å, b = 7.54767(18) Å, c = 7.71128(18) Å, β = 90.678(3)°, V = 426.348(19) Å3, and Z = 8.

Zinkgruvanite, a barium manganese iron silicate with sulfate, is a new mineral found in drill core samples from the Zinkgruvan zinc, lead and silver mine in Sweden. It is associated with other minerals like baryte, barytocalcite, diopside and sulfide minerals. It occurs as flattened and elongated crystals up to 1 mm. It is almost black. Zinkgruvanite is closely related to the mineral yoshimuraite and based on its crystal structure, grouped with the ericssonite group of minerals.

This is the first description of the new mineral kahlenbergite, found in the Hatrurim Basin, Israel, which is a region with unusual pyrometamorphic rocks. Kahlenbergite is chemically and structurally characterized. It is very similar to β-alumina compounds, which are synthetic materials known for their properties as fast ion conductors.

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. In this study, artificial synthetic experiments have been conducted to explore the formation process of wumuite and tewite. Wumuite was speculated to be formed by a metasomatic reaction between W-rich hydrothermal fluids and the potassium feldspar in the monzonite.

Luxembourgite, ideally AgCuPbBi4Se8, is a new selenide discovered at Bivels, Grand Duchy of Luxembourg. The mineral forms tiny fibres deposited on dolomite crystals. Its crystal structure is similar to those of litochlebite and watkinsonite, and can be described as an alternation of two types of anionic layers: a pseudotetragonal layer four atoms thick and a pseudohexagonal layer one atom thick. The species named for the city of Luxembourg, close to its locality of discovery.

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.

This paper describes the characterization of a new mineral from the Oumlil mine in the Bou Azzer cobalt mining district in Morocco. This mining district is one of the world's largest producers of the important element cobalt. This study on the new mineral halilsarpite provides useful information on the results of chemical weathering processes on the primary arsenide minerals at the mine.

Short summary
The paper reports the type description of the new mineral species graulichite-(La). This is a new addition to the dussertite group within the alunite supergroup, and its discovery improves our knowledge on the crystal chemistry of this important supergroup of minerals, having both technological and environmental applications.
