Abstract

Language:

The crystal structures of jarosite and svanbergite have been refined through detailed analysis to reveal the geometrical relationships involving sulfur tetrahedra within each mineral. In the case of jarosite, it was found that the geometry is significantly influenced by the presence of octahedral cations. The study highlights that the sulfur tetrahedra in jarosite expand to near maximum dimensions, exhibiting a comparable size to that of phosphorus tetrahedra. The research further compares the six refined structures of alunite-type minerals, including alunite, goyazite, crandallite, and woodhouseite, along with the two studied minerals. A critical observation from this investigation is that jarosite, characterized by iron octahedra, displays unique structural behavior that deviates from customary expectations, whereas the structures containing aluminum octahedra align more predictably with crystallographic principles. This specificity implies a notable flexibility within the alunite-type structures, allowing for various ions to adopt adaptively different geometries, which underscores the structural versatility facilitating the crystallization of numerous minerals in this category.
