This paper reports a new natural oxyphosphate, the first mineral that crystallizes in the α-Fe2PO5 structure type. It is isotypic to a series of synthetic oxyphosphates with promising magnetic and electrochemical properties.

Andreybulakhite, ideally Ni(C2O4) · 2H2O, is a new oxalate mineral, which was discovered on the Kola Peninsula, Russia. Andreybulakhite forms segregations of crystals up to 2 × 1 × 1 mm in size disseminated within the fruiting bodies of Lecanora cf. polytropa lichen, whose colonies overgrow the oxidized surfaces of pyrrhotite–pentlandite–chalcopyrite ore. Andreybulakhite is named in honour of Andrey Glebovich Bulakh of Saint Petersburg State University.

A database of a modern metastable cold-water mineral (ikaite) and its replacement mineral (glendonite) spanning 540 million years has been created to understand their distribution in space and time. A significant body of evidence suggests that glendonite occurrences are restricted mainly to cold-water settings; however they do not occur during every glaciation or cooling event reported from the Phanerozoic. This compilation improves our understanding of climatic conditions of the past.

The nolanite supergroup has been established and approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association. It contains eight mineral species with the nolanite-type structure. The nolanite supergroup is subdivided into three groups (nolanite, kamiokite, and rinmanite groups). After significant changes, the classification of the nolanite supergroup was approved again.

Ellinaite, a natural analog of β-CaCr2O4, was discovered at Hatrurim Basin, Israel, and in an inclusion within the super-deep diamond from the Sorriso Creek placer, Brazil. Chemical composition, structural data and physical properties are given for this mineral. It is related to multiple oxides AB2O4 with tunnel structure. This group now includes eight minerals. The overview of ellinaite from all localities suggests different PT–X–fO2 conditions for the mineral and its host rocks.

We found Ca- and S-rich rhabdophane in the upper part of the oxidation zone of a sulfide occurrence, where it forms spherules up to 35 µm in size and aggregates in fractures in goethite. Its formation is probably associated with desorption of REEs from Fe3+ oxyhydroxides and clay minerals in the oxidation zone and the influx of P from the soil as well as from the precursor rocks. The enrichment with REE phosphate in the studied case is similar to that in REE regolith-hosted deposits.

Carbonophosphates (sidorenkite, bonshtedtite, and bradleyite) with the general formula Na3MCO3PO4 (M is Mn, Fe, and Mg) are often found in inclusions of carbonatite and kimberlite minerals. This article presents the results of Raman spectroscopic study and a simple algorithm for diagnosing mineral phases of the carbonophosphate group. This work may be of interest both to researchers of carbonatites and/or kimberlites and to a wide range of specialists in the field of Raman spectroscopy.

Short summary
Kayupovaite is a new mineral named in honor of Maria Mikhailovna Kayupova (1921–1980), the mineralogist who studied the Ushkatyn-III deposit (Kazakhstan), the type of locality of the described mineral. Kayupovaite is monoclinic and of space group C2/c. The mineral belongs to the group of modulated manganese phyllosilicates and is structurally related to stilpnomelane. The absence of iron in the mineral is a result of oxidative Mn–Fe fractionation during the formation of braunite-rich Mn ores.
