Malachite ps azurite
description: LOCALITY: Sir Dominic Mine, Arkaroola, South Australia (state), Australia 1 1/4" tall Both ends of this pseudomorph display what appear to be hopper faces. This trait is one that the author cannot recall seeing in any other malachite pseudomorph after azurite. Hopper terminations generally result when the growth rate at the edges of a crystal exceeds the growth rate in the interior. The hopper terminations of this specimen may have resulted from selective dissolution of the end faces (Brian England, verbal communication)
