...Cristian Biagioni; Ferdinando Bosi; Ulf Hålenius; Marco Pasero Abstract The crystal structure of svabite, ideally Ca 5 (AsO 4 ) 3 F, was studied using a specimen from the Jakobsberg mine, Värmland, Sweden, by means of single-crystal X-ray diffraction data. The structure was refined to R 1 = 0.032...

The Nordmark area lies about fifteen kilometers north of Filipstad, and Langban twenty...

...) , johnbaumite may have been found about 90 years before its formal description. In the paper published in 1891 Sjögren described the occurrence of svabite at the Harstigen mine, whereas in the work of 1892 he reported the occurrence of svabite at Harstigen and at the Jakobsberg mine. The chemical analyses...

Anthropogenic margarosanite occurs on corroded lead bullets (Mera et al. , 2015 ). Further studies on Franklin type specimens clarified the crystallography...
