Anthonyite from
Centennial Mine, Centennial Heights, Calumet Township, Houghton County, Michigan, USA


Locality type:Mine
Classification
Species:Anthonyite
Formula:Cu(OH,Cl)2 · 3H2O
Comments:Anthonyite is found in pockets or as encrustations in basalt and occurs as delicate, lavender prisms up to 0.5 mm in length embedded and encrusted by an unidentified waxy green basic copper chloride. Other directly associated minerals are copper, cuprite, paratacamite, and an unidentified blue, isotropic, basic copper chlorite.

Many of the crystals are curved one or more times along the c axis; the plane of curvature is {010} and bending apparently occurs readily on the perfect cleavage on {100}
