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.

Short summary
Based on the analysis of the morphology and mixing structure of the activated and unactivated particles, our results emphasize the role of in-cloud processes in the chemistry and microphysical properties of individual activated particles. Given that organic coatings may determine the particle hygroscopicity and heterogeneous chemical reactivity, the increase of OM-shelled particles upon in-cloud processes should have considerable implications for their evolution and climate impact.

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.

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. Research in the Hatrurim Basin is needed to understand the complex mechanisms that created this mineralogically diverse

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.

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.

Short summary
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. According to the hierarchical scheme for perovskite supergroup minerals, liguowuite is the first reported example of A-site vacant single oxide, i.e., a new perovskite subgroup.
