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.

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.

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.

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.

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.

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.

The purpose of this paper is to present new perspectives on the pressure estimate of submicrometric white mica using energy-dispersive X-ray spectroscopy performed by a transmission electron microscope. This technique aims to explore the mineral chemistry of single grains whose dimensions do not allow for analysis by microprobe. The validation of this procedure opens a wide range of applications hitherto untested due to instrumental incompatibility with mineral phases smaller than 5 µm.

The study of minerals at microscopic and nanoscopic scales is essential for understanding the processes behind their formation. Indeed, by examining minerals in such detail, it is possible to uncover the underlying mechanisms that govern mineral development, from crystal growth to chemical reactions, providing insights into broader geological and environmental processes. The understanding of these processes is especially crucial when minerals contain elements valuable to various industries.

This work deals with a challenging case of a commercial clay from Gomsiqe–Puka (Albania) contaminated by mineral fibres. Detection and quantification of asbestos in this material push the boundaries of current experimental methods. Using TEM, micro-Raman spectroscopy, and EPMA, we identified the presence of asbestos tremolite, along with a rare fibrous variety of diopside. The impact of milling on the detection and quantification of mineral fibres was also evaluated.

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.

We carried out theoretical calculations of the vibrational and thermophysical properties of Mg2SiO4 ringwoodite, a major mineral phase of the Earth's mantle transition zone. We tried to understand why current data on volume thermal expansion are still controversial by performing a detailed analysis of vibrational spectra. We proposed a reliable parametrization for thermal expansivity of ringwoodite in the transition zone which could be useful for numerical simulations of mantle convection.

Short summary
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.
