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.

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.

Western Norwegian “diamond facies” eclogite contains tiny mineral inclusions of quartz and amphibole lamellae that are not stable in the diamond field. Low trace amounts of water in the lamellae-bearing host minerals suggest that the inclusion microstructure was not formed by fluid infiltration but by dehydration during early exhumation of these rocks. Some samples with higher water content argue that a late fluid overprint was spatially restricted and erased evidence of extreme metamorphism.

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.

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.

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.

Dutrowite is the first tourmaline supergroup minerals having Ti as a species-defining chemical constituent. Its finding improves our knowledge on the crystal chemistry of this important mineral group and allows us to achieve a better picture of the mechanisms favouring the incorporation of Ti.

Short summary
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.
