Phosgenites in varieties of shapes. Self-collected in 2009. Richard Green photo and collection.
A terrific place to collect slags. Just walk on the beach at low tide and pick up the brownish nodules. Self-collected in 2009. Richard Green photo and collection.
Very rare from the smelter ID by XRD.

Minute Cumengeite crystals with corroded (Pb-Cl?) white-yellow mineral.
A tentative identification of Thorikosite as a single disc-like pale yellow crystal with black looking Phosgenite crystals. The white crystalline crust is undetermined.
Intergrown platy crystals of Pseudoboleite probably, with barrel-like crystals of Phosgenite. Unusual light green colour for the spices, maybe due to alteration?
Crystals of Diaboleite with a Laurionite crystal on a druse of an undefined mineral.
Cerussite associated with yellow maybe Laurionite.
The lower very tiny crystal group showing the platy crystals developed in 90deg twinning for Pseudoboleite. On Fe-oxide coated Laurionite crystals.
Phosgenite with tiny 'Cumengeite' crystals and an 'amorphous' yellow mineral
Prismatic crystals of Phosgenite with a crystal druse of 'Cumengeite' and a yellow 'amorphous' mineral with undefined Fe-oxides.
Phosgenite on tiny octahedral yellow and yellow-brown Römerite like mineral possibly.
Blocky Phosgenite crystals with radial groups of maybe Aragonite.
Group of tetragonal phosgenite crystals on slag. Photographed by and in the collection of Douglas Merson.
