Ginelfite is a new Ag–Fe–Tl–Pb sulfosalt described from the hydrothermal deposit of Jas Roux (France). It belongs to the so-called boxwork sulfosalts, a group of species showing the highest structural complexity among this group of chalcogenides. This very complex structure is probably stabilized by the occurrence of minor chemical constituents (Tl, Fe) occupying specific structural positions.

Dacostaite is a new fluoride–arsenate mineral found in the Sb(Au) deposit of the Cetine di Cotorniano Mine (Tuscany, Italy). It shows a novel crystal structure formed by heteropolyhedral layers and isolated Mg(H2O)6 groups connected by H bonds. The heteropolyhedral layers are similar to those occurring in alunite-supergroup minerals, and this is a further example of the ability of nature to use similar modules in forming the large number of currently known structural arrangements.

Nannoniite, Al2(OH)5F, is a new mineral species discovered in the Cetine di Cotorniano mine (Tuscany, Italy). Its description was possible through a multi-technique approach, and its crystal structure was solved through three-dimensional electron diffraction, revealing close relations with gibbsite. The partial replacement of (OH) by F induces subtle by detectable structural changes. This study reveals that Al hydroxides could be a source of F in geological environments.

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.

This study describes the elbaite neotype, found in crystals from a site on Elba island, Italy. Researchers analyzed these nearly colorless crystals and found that their formation was influenced by earlier changes in the surrounding rock. As different minerals formed first, they set the stage for elbaite to develop later in deeper spaces. This work helps us understand how changes in the local environment affect how and when certain minerals grow.

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.

Zvěstovite-(Fe) is a new, Ag-rich, member of the tetrahedrite group, the most widespread sulfosalts in ore deposits. Its discovery stresses the chemical variability of this mineral group, allowing for a better understanding of the structural plasticity of these compounds, which are able to host a plethora of different elements typical of hydrothermal environments.

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.

Short summary
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.

Short summary
Batoniite is a new mineral species belonging to the Al2O3–SO3–H2O ternary system, first found in the Cetine di Cotorniano Mine (Tuscany, Italy). This hydrated Al sulfate shows a novel crystal structure, characterized by Al octamers, so far reported in only synthetic compounds.
