Type Locality. Polished section & analysis of this very rare lead-iron analogue of pentlandite, from the type locality, present as typical submicroscopic grains embedded in massive sulphides. Ex Raymond Hodgson Collection (4272) obtained in 2007....
A lot going on here. Orange phantoms in quartz crystals. These are coated in white drusy quartz. Then there are colourless quartz scepters. But not just at the tips. There are tiny little sceptres ALONG...

Several dozen of these little nuggets, at least, mounted on a square of stiff yellow paper glued to the top of a cork pedestal in a two piece black plastic micromount display case. From the...
This NEW SPECIES occurs as very tiny, grass-green to light green aggregates of coarse prismatic to acicular crystals on volcanic scoria, typically with darker green undefined Cu-sulfates and occasionally black tenorite. Formula: Cu4O(AsO4)2 ? orthorhombic...
Another NEW SPECIES from this bizarre geological environment in Kamchatka, chrysothallite occurs as extremely small, bright golden yellow, equant micro crystals perched in scoria vugs, often with olive green belloite and occasionally other rare species...
