Short summary
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.

Macraeite is the fourth type mineral to be described from the Mangualde pegmatite, Portugal, and is the first paulkerrite-group mineral to be characterised from the locality. Its crystal structure has been refined using synchrotron diffraction data, and its chemical analysis, Raman spectrum, and optical properties are reported.

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.

Regerite is the first new mineral species to be described from the Kreuzberg pegmatite, Pleystein, in the Oberpfalz, Bavaria. It has been characterised using electron microprobe analysis, Raman spectroscopy, optical measurements and a synchrotron-based single-crystal structure refinement. The structure type for regerite has not been previously reported.

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.

This paper describes the characterisation of a new mineral from a South Australian phosphate quarry. The characterisation included chemical analyses, infrared spectroscopy, and a determination and refinement of the crystal structure. The results showed that the mineral has a unique crystal chemistry, but it is closely related to the well-known phosphate mineral crandallite.

Karlseifertite is a new member of the dussertite group of the alunite supergroup from Tsumeb, Namibia. It is the first member of the dussertite group to be described based upon valency-imposed double site occupancy in the octahedrally coordinated cation site. It is also the first member of the alunite supergroup containing essential Ge.

Rotherkopfite is the first member of the neptunite group that does not contain lithium in its chemical formula. It was found at Rother Kopf, Eifel volcanic fields, Germany, where in occurs in cavities in a quartz–sanidine fragment embedded in a volcanic rock. Rotherkopfite occurs as dark brownish-red crystals, up to about 0.2 mm across. The intriguing crystal structure is based on two interwoven three-dimensional frameworks.

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.
