In this work, we present the most iron-rich chrysoberyl discovered to date, found in the Sabatini Volcanic Complex (Latium, Italy). We provide a comprehensive overview of its chemical, structural, spectroscopic, and optical properties. The characterization of this chrysoberyl reveals several unique features, offering valuable insights into its genetic model and geochemical constraints, which are consistent with existing literature on the Sabatini complex and with ongoing research.

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.

Friisite is a newly identified mineral, with the chemical formula Pb8Al3Si8O27Cl3, from the Långban mine in Sweden, found as tiny, white, flaky grains within a skarn matrix alongside jagoite and other silicates. It has a sub-adamantine luster, perfect basal cleavage, a hardness of 4–5, and a high density of 5.54 g cm−³. Structurally it is a hexagonal phyllosilicate, closely related to jagoite in a polysomatic series. The mineral is named in honor of Danish mineralogist Henrik Friis.

The mineral clino-ferro-suenoite, with the chemical formula ◻Mn2Fe2+5Si8O22(OH)2, was historically named “dannemorite” or “manganogrunerite” and is a member of the amphibole supergroup. It is now formally approved by the International Mineralogical Association. It occurs in iron–manganese-bearing rock from the Hilläng mines, Dalarna, Sweden, and is associated with the minerals fayalite, spessartine, ferro-actinolite, calcite, magnetite and pyrite. It formed by replacement of Mn-bearing fayalite.

Technology for producing energy with zero-carbon emissions must be developed in light of the current climate emergency. Using recyclable metal fuels, such as magnesium (Mg), is one practical solution. Metals can therefore be seen as regenerable fuels and new energy vectors since the energy they contain can be transferred and released through metal combustion. To optimize the particle trapping capacity of the investigated system, we successfully characterized magnesium oxide (MgO) crystals.

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.

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.

Short summary
The article provides the standard description of bonacinaite, Sc3+(AsO4)·2H2O, the first natural scandium arsenate. The new mineral species was found in a few specimens in the dumps of the old Varenche Mine, Valle d'Aosta, Italy, which is therefore the type locality and the only locality in the world. Bonacinaite forms colourless (with faint to distinct violet tints), pseudohexagonal, thick tabular crystals, up to 0.25 mm in size, or as small, faintly violet lath-shaped crystals.
