Fassinaite (identified by Raman spectroscopy) as a light olive-green group, height 1.2 mm, in galena pocket. I collected this specimen in Oct. 2011 in a small mineralized area near the adit of "Galleria n° 2 - Concessione Lombardo". Collection and photo A. Zordan.

One of two very small tufts of fassinaite crystals (the second one has been sacrificed for EDS and subsequent SXRD analyses) in a void in corroded galena. Size of the tuft approx. 0.3 mm. Collected by Carsten Slotta in the early 1990s long before the mineral was recognized as a new species. Collection and photo Stephan Wolfsried.

Small sprays of acicular fassinaite crystals (SXRD-analysed). The colourless, partly sword-shaped crystals in the vicinity are anglesite (SXRD-analysed). Photo Harald Schillhammer. Only a single specimen of fassinaite has been identified so far in the Waitschach slags, but as the photo shows, the mineral appears similar to acicular cerussite, ...

Euhedral colorless chisel-shaped fassinaite crystals that are only visible as sharp lustrous faces. Subhedral transparent pale yellow sulphur and orange sphalerite are also in association and the whole assemblage sits atop galena. Fassinaite is one of only five accepted thiosulfate-bearing minerals, and if the Mindat database is current, this may ...

Microscopic white bundle-forming needles belong to fassinaite - a relatively "young" mineral (2011 approval), one of three undoubtedly confirmed minerals containing the thiosulfate (SO3S 2-) anion (the other two ones are the quite chemically similar sidpietersite and much more complex steverustite; bazhenovite is only supposed to contain the ...
