Anglesite


Chemistry: PbSO4
Size: 45 mm
Owner: Mariusz Oleszczuk
Photographer: Mariusz Oleszczuk

Colourless, transparent tabular crystals of anglesite (to 25 mm), on a matrix that consists mainly of galena.  

Some sparsely distributed crystals of copper secondaries are present on the matrix:  blue crystals of what appears to be linarite (?), and blue-green crystals of possible posnjakite (?).  There are also a few yellow-orange microcrystals of an unidentified mineral resting on the matrix at the top of the specimen (as seen in the photograph).
