Cubanite

CuFe2S3
Orthorhombic heart IMA grandfathered

Cubanite is a sulfide mineral with the chemical formula copper iron trisulfide. It crystallizes in the orthorhombic system and is characterized by a metallic luster, black streak, and typically a brassy yellow to reddish-brown color. It has a hardness of approximately 3.5 to 4 on the Mohs scale and a relatively high density. Cubanite belongs to the sulfide class of minerals and is classified under the Strunz system as 2.CB.55a. It is commonly found in association with other sulfide minerals and is known for its distinctive cubic or octahedral crystal habit when well-formed.

Etymology

Cubanite is named after Cuba, where it was first discovered. The mineral was recognized and named in reference to its type locality in that country.

Geological genesis

As a sulfide mineral, Cubanite typically forms in hydrothermal environments associated with the deposition of metal sulfides. It is commonly found in veins and in association with other sulfide minerals, suggesting a genesis related to hydrothermal activity in igneous or metamorphic settings.

Occurrence

Cubanite is found in various sulfide-rich deposits, particularly in association with other copper and iron sulfides. It is most commonly associated with hydrothermal veins and is known to occur in several mineral districts worldwide.
