Also given as Cu(C2O4) · 0.4H2O.
Colour:
Turquoise-green, blue to green
Specific Gravity:
3.43 (Calculated)
Crystal System:
Orthorhombic
Name:
Named after the type locality (Mooloo Downs Station, Australia).
Compare other Cu-bearing oxalate minerals: middlebackite, fiemmeite, wheatleyite, and antipinite.
May be a biomineral formed by the action of lichens (Acarospora rugulosa, Lecidea inops, Lecidea lactea) growing on cupriferous rocks (vide Burford et al., 2003).
