Naldrettite

Sulfide mineral

Naldrettite is a mineral with a chemical formula of Pd2Sb. It is named after Anthony J. Naldrett (born 1933), a professor, who has made significant contributions to the International Mineralogical Association (IMA). Naldrettite is a new intermetallic mineral from the Mesamax Northwest deposit, Ungava region, Québec , Canada. Mineralization takes place around the base of basaltic dyke margins. Naldrettite is economically important because of its chemical composition (Pd2Sb). The sample in which the new mineral was discovered had high platinum group elements (PGEs) with palladium

Naldrettite occurs as anhedral grains that are commonly attached to sulfide minerals and are associated with clinochlore crystal system This means that all of the edge lengths (a,b,c) of the unit cell are different in length and intersect at right angles to each other. The mineral is metallic, opaque, appears bright creamy white under plane polarized light, has weak bireflectance, and does not exhibit internal reflections.
