Digital image in reflected plane polarized light of jonassonite with ikunolite and native bismuth. These occur together with a rather porous 'melnikovitic' marcasite-pyrite mixture. Horizontal field is about 200 microns. This image was taken of the area measured for reflectance and published in the original description of jonassonite in ...

Euhedral crystal of zipserite (Zps) embedded in native bismuth (Bi) associated with bismuthinite (Bmt) from the type locality, Alsó-Rózsa adit, Nagybörzsöny, Hungary. Part of holotype material which I collected at the dumps of the Alsó-Rózsa adit in June 2007. All minerals were confirmed by EPMA-WDS. BSE image on JEOL JXA 8530F electron ...

Analysed ikunolite sample showing the perfect cleavage. There is a slight change of Bi/Se distribution which is indicated by the brighter area. This part is more Bi dominant with a lower amount of Se.
