Fluormacraeite is the first type mineral to be described from the Plößberg pegmatite, Upper Palatinate, Bavaria, Germany. The crystal structure of fluormacraeite has been refined using synchrotron data that has resolved a small monoclinic distortion due to ordering of K and H2O. The general crystal–chemical properties of the monoclinic paulkerrite-group minerals are discussed.

The paper describes the characterisation of fluor-rewitzerite, a new mineral species belonging to the paulkerrite group. The crystal structure of fluor-rewitzerite has been refined using microfocus synchrotron diffraction data, which allowed 25 of the possible 30 H atoms to be located, thus establishing key features of the H bonding. Crystallochemical trends are reviewed for seven recently characterised monoclinic paulkerrite-group minerals.

Manganrockbridgeite, Mn2+2Fe3+3(PO4)3(OH)4(H2O), a new member of the rockbridgeite group, has been characterised using electron microprobe analyses, Mössbauer spectroscopy, optical properties and single-crystal X-ray diffraction. Whereas other rockbridgeite-group minerals have orthorhombic symmetry with a statistical distribution of 50%Fe3+/50% vacancies in M3-site octahedra, monoclinic manganrockbridgeite has full ordering of Fe3+ and vacancies in alternate M3 sites along the 5.2 Å axis.

The paper gives a characterisation of the new mineral species, whiteite-(CaMnFe), which has recently been approved as a new mineral (proposal IMA2022-077). The study included a single-crystal structure refinement that, when combined with electron microprobe analyses, confirmed that the mineral was a new member of the whiteite subgroup of the jahnsite group of minerals. Relationships between the crystal structure and the unit-cell parameters for the whiteite-subgroup minerals are discussed.

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 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.

Skogbyite, with the chemical formula Zr(Mg2+2Mn3+4)SiO12, is a new species in the braunite group of minerals. It was discovered in a complex mineral assemblage, essentially a very poor manganese ore, from the Långban Fe–Mn oxide deposit, Värmland County, Bergslagen ore province, Sweden. It is named after the Swedish mineralogist Henrik Skogby (b. 1956). It is a new mineral attesting to the localised mobility and reactivity of zirconium under very special geological conditions.

The compositional variation in a multi-coloured, zoned tourmaline from the Cruzeiro pegmatite, Brazil, reflects melt chemical evolution during the entire pegmatite differentiation. In uncontaminated granitic pegmatite systems such as that of Cruzeiro, the compositional evolution of tourmaline progresses from schorl to fluor-elbaite, rather than directly from schorl to elbaite, to reflect co-enrichment in Li and F during fractional crystallization.

The discovery of the K-dominant tourmaline maruyamaite with microdiamond inclusions suggested its ultrahigh-pressure formation. We analyzed the role of K in the tourmaline structure, with a special focus on its stability. High pressure is necessary to squeeze the large cation K+ in the stiff framework of tourmaline, although K is the underdog component if Na+ is present in the mineralizing fluid. K-tourmaline is stable at high pressure, overcoming the stereotype of a mere crustal component.

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.

Short summary
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.

Short summary
The paper describes the formal establishment of the paulkerrite group of minerals and its nomenclature. It includes the application of a site-merging procedure, coupled with a site-total-charge analysis, to obtain unambiguous end-member formulae. Application of the procedure has resulted in the revision of the end-member formulae for several of the group members.
