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.

We described two new minerals, igelströmite and manganoschafarzikite, from the Långban manganese–iron deposit in Värmland, Sweden. The chemical formulae are Fe³⁺(Sb³⁺Pb²⁺)O₄ and  Mn²⁺Sb³⁺₂O₄, respectively. They belong to a new mineral group, where all members have the same crystal structure. It is called the minium group, after the lead-oxide mineral that is the oldest known substance of this kind.

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.
