Crystallography of Chalcoalumite

Crystal System:Monoclinic
Class (H-M):2 - Sphenoidal
Space Group:P21 {P1 1 21} {P21} {P1 21 1}
Cell Parameters:a = 17.09Å, b = 8.92Å, c = 10.22Å
β = 95.88°
Ratio:a:b:c = 1.916 : 1 : 1.146
Unit Cell Volume:V 1,549.77 ų (Calculated from Unit Cell)
Morphology:Occurs as rather porous, botryoidal crusts comprised of minute, matted fibers. Relatively large, lath-like crystals coat the outsides of the structures.
Twinning:Twinning of the laths sometimes apparent with the composition face parallel to the long edge and nearly normal to the flat face. These exhibit re-entrant angles, with symmetrical faces and extinction.
