Allactite


Allactite is a hydrated manganese arsenate. Sjögren (1884) used material from the nearby Moss mine to describe the mineral, naming it for the Greek word for change in allusion to the strong pleochroism. Here allactite forms bladed crystals to 2 mm, forming a mass of crystals. Two separate pockets shows well developed transparent crystals.
