We described two new minerals, igelströmite and manganoschafarzikite, from the Långban manganese–iron deposit in Värmland, Sweden. The chemical formulae are Fe3+(Sb3+Pb2+)O4 and Mn2+Sb3+2O4, respectively. They belong to a new mineral group, where all members have the same crystal structure. It is called the minium group, after the lead-oxide mineral that is the oldest known substance of this kind.

We report the description and the characterization of a new mineral species, found in a rock sample from the geological formation called the Pilanesberg Complex, South Africa. This is a silicate mineral that contains a significant amount of sodium, calcium, iron, titanium and fluorine. Its atomic structure shows that it is related to other wöhlerite-group minerals. This work provides new insights into the crystallization conditions that ruled the formation of the Pilanesberg complex.

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 reliquary crown, hosted in the diocesan museum of Namur (Belgium), was produced during the beginning of the 13th century. This beautiful piece of goldsmithery is decorated with approximately 400 pearls and coloured stones which were investigated by Raman and pXRF techniques. Emeralds, pink spinels, sapphires, almandine garnets, turquoises, and pearls were identified. The gemstones, contemporary with the crown, probably arrived in Europe by the silk trade road.

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.

The As4S6 molecule was missing in the reported structures of crystalline As chalcogenides. Here we report the first occurrence of the As4S6 molecule together with the other known As4Sn (n = 3, 4, 5) molecules randomly replacing each other in the crystalline structure of a new monoclinic product obtained by the light-induced alteration of the mineral alacranite, As8S9.

The structure of beryl has been a topic of research for decades but is still not entirely understood. This especially applies to substitutions by Fe ions and the occupation of the channels of beryl by H2O and alkalis. The growing amount of studies makes it difficult to gain an overview on these topics. Therefore, this article reviews the current consensus and debates found in the literature.

To explore the compositional constraints on Cl incorporation into amphiboles, which can be used to characterize transient brines, amphiboles were synthesized with a broad range of Cl concentrations. Amphibole Cl was found to be dependent on the Fe2+,3+ content, but not the tetrahedral Al content or K / Na ratio. Cl incorporation was found to contract the unit cell along a and expand it along b and c. Molar volumes were derived for endmember Cl-amphiboles using multivariate regressions.

Minerals formed by weathering of toxic materials, of either natural or human origin, act as storage containers for toxic elements. In this work, we investigated properties of common minerals which store and release arsenic in the environment. The data presented here will allow for improved modeling of the polluted sites and for better remediation strategies that could be applied to minimize the impact of the pollution on the environment.

Using an innovative multi-analytical approach, we investigated the trace elements composition of spinel-group minerals in different ultramafic rocks from the Voltri Massif (Central Liguria, NW Italy). The knowledge of the trace elements within these minerals has an interesting implication both in petrological, mineralogical, and geochemical studies as well as environmental fields, since these elements can be potentially toxic and released into the environment during weathering processes.

Elba tourmaline crystals commonly display a sharp transition to dark colors at the analogous termination, but the mechanisms leading to the formation of such terminations are unclear. Here we propose a general genetic model in which, as a consequence of a pocket rupture event, chemical alteration of early formed Fe-/Mn-rich minerals in the enclosing pegmatite was responsible for the release of Fe and/or Mn in the geochemical system, allowing the formation of the late-stage dark terminations.

Paramontroseite is a V dioxide (a = 4.8960(14) Å, b = 9.395(3) Å, c = 2.9163(5) Å, V = 134.14(6) Å3; space group Pbnm). The sample under investigation (Prachovice mine, Czech Republic) bears 20 wt % of Fe2O3, and the Fe atoms occupy tetrahedral sites arranged in the
emptychannel along z. Thermal expansion is anisotropic. At T > 350 °C, paramontroseite decomposes and two new phases form: V2O5 (V-pentoxide) and V4Fe2O13 (Fe-tetrapolyvanadate).

Synthetic lepidolites and Li-muscovites were characterised by nuclear magnetic resonance (NMR) spectroscopy and X-ray diffraction. Both Li and F / OH content influence the occurrence of the impurity phases. A solid solution series exists for lepidolites with polylithionite and trilithionite as endmembers but does not between trilithionite and muscovite. NMR investigations indicate there is a preference for incorporating fluorine and OH groups near Li-rich and Al-rich environments, respectively.

Feldspars constitute about 60 % of the earth's crust. Na-feldspar, Na[AlSi3O8], is central to this mineral group. Its structural response to changing conditions of temperature and pressure is complicated. In particular, this applies to the distribution of Al and Si on the atomic sites of its crystal structure. We clarify how this distribution varies in thermodynamic equilibrium with external conditions and provide procedures that allow easy determination of the atomic distribution.

Short summary
Ardennite is a rare Mn-rich aluminosilicate that was originally described in Salmchâteau, Belgium. In the last few years, new samples of ardennites have been found at several localities close to Salmchâteau. These samples were analysed by electron microprobe, single-crystal X-ray diffraction, and infrared spectroscopy. The results given in this paper allow us to identify the main substitution mechanisms that occur in Belgian ardennites and to discuss the nomenclature of the ardennite group.
