Abstract
Chemical (EPM analyses), crystallographic and structural (single crystal X-Ray diffraction) investigations carried out on a specimen of "johnstrupite" from the Barkevik skerry, taken from Brøgger's own collection, pointed to its identity with rinkite and indicated the ideal crystal chemical formula Ti(Na2Ca)(Ca3REE)(Si2O7)2(F3O).File in questo prodotto:
