Hollandite
Hollandite is a complex oxide mineral with the chemical formula Ba(Mn^4⁺6Mn^3⁺2)O16, indicating the presence of barium, manganese in both +4 and +3 oxidation states, and oxygen. It crystallizes in the monoclinic system and is classified in the Strunz system as 4.DK.05a. The mineral exhibits a hardness of approximately 5.5 to 6.5 on the Mohs scale, a density of around 4.1 to 4.3 g/cm³, and a metallic to submetallic luster. It typically appears black to dark brown in color. Hollandite is a member of the pyrochlore group and is known for its prismatic crystal habit and striated surfaces.

Etymology
Hollandite is named after Thomas Henry Holland, a British mineralogist and chemist. The mineral was recognized and named in his honor for his contributions to the field of mineralogy.
Geological genesis
As an oxide mineral within the pyrochlore group, hollandite typically forms in igneous and metamorphic environments, particularly in alkaline rocks and pegmatites. Its formation is associated with high-temperature processes involving the oxidation of manganese.
