... are the dimorphous pairs cornwallite and cornubite [Cu 5 (AsO 4 ) 2 (OH) 4 ] and clinoclase and gilmarite [Cu 3 AsO 4 (OH) 3 ]. Gilmarite is extremely rare, having been reported from a single locality in France ( Sarp and Černý 1999 ). Olivenite is monoclinic (pseudo-orthorhombic), space group P 2 1 / n ( Berry...
