Moolooite

Moolooite is a rare blue-green mineral with the formula Cu⁺⁺(C₂O₄)·n(H₂O) (n<1) (making it a hydrated copper oxalate). It was discovered by Richard M Clarke and Ian R Williams in Bunbury Well, Mooloo Downs station, Murchison, Western Australia in 1986.[1] It has an orthorhombic crystalline structure, and is formed by the interaction of bird guano with weathering copper sulfides.

A second occurrence is reported from the Sainte-Marie-aux-Mines silver mining district of Vosges Mountains, France.[1]
