[4] It was named after Belgian mineralogist Aimé Marthoz (1894–1962), former Director-general of the Union Minière du Haut Katanga (UMHK).

[3] It is specifically found in the zones of oxidation of the Musonoi deposit in Katanga, Africa.

[6] Marthozite is orthorhombic, meaning that it has three axes of unequal lengths all orthogonal to each other.

Since it is orthorhombic, marthozite is biaxial, meaning that it has three different indices of refraction.

[7] Marthozite shows pleochroism from yellowish brown to greenish yellow.
