The occurrence of sulfate minerals associated with the pyrite ores of the southern Apuan
Alps has been known since the 19th century but modern mineralogical studies started only …

Using combination of acid-solution, high-temperature oxide-melt, relaxation, and differential
scanning calorimetry, we have determined the thermodynamic properties of all phases in the …

This chapter contains IR spectra of mineral species and varieties, most of which was not
included in the preceding reference book (Chukanov in Infrared spectra of mineral species …

The thermal behavior of melanterite from the Fornovolasco mine (Tuscany, Italy) has been
investigated via differential thermal analysis (DTA), thermogravimetry (TG), in situ high …

Abstract Coquimbite, AlFe 3+ 3 (SO 4) 6 (H 2 O) 12⋅ 6H 2 O, was considered as a pure Fe
3+ hydrated sulfate. However, previous mineralogical studies pointed out the occurrence of …

Parabutlerite, orthorhombic FeIIISO4 (OH)· 2H2O, has been reinvestigated using single-
crystal X-ray diffraction. The structure of parabutlerite is commensurately modulated, with a …

Abstract Khademite, ideally Al (SO 4) F (H 2 O) 5, from the Monte Arsiccio mine, Apuan Alps,
Tuscany, Italy, has been characterised through quantitative electron microprobe analysis …

The crystal structure of ferrinatrite, Na 3 [Fe (SO 4) 3]· 3H 2 O, was refined based on a new
single-crystal X-ray diffraction experiment on a sample from the type locality Sierra Gorda …

Khademite and rostite are orthorhombic minerals Al (SO) 4 F· 5H 2 O and Al (SO) 4 OH· 5H 2
O, respectively. Libušín is a type locality of rostite but recent studies have only confirmed the …

A hydrous ferric sulfate with a formula Fe (SO 4)(OH)⋅ 2H 2 O was discovered in the
supergene zone of the Khangalas gold ore deposit, Yakutia, Russia. Studies of the mineral …
