More Hidden Collection

Mineral Matters #704

You all know how much I like my Hidden Collection! 😁

Well here is another to add to it.

Labelled simply as scolecite, Arvigo, Switzerland. This specimen contains so much more under the microscope.

In addition to the scolecite crystals (you can see their terminations top left), there is blue prehnite sprinkled with pyrite, green epidote crystals, green worms of chlorite, and colourless albite. And I think there is a tiny orange titanite on the prehnite too...

Below: Prehnite, Epidote, Pyrite, Scolecite, Chlorite, Albite, Titanite(?), Arvigo, Calanca Valley, Misox, Grischun, Switzerland. Width of view 3mm.
