Alabandite
Definition
A rare mineral from the sulfide class, consisting of a native manganese sulfide with the chemical formula MnS; it crystallizes in the cubic system and usually occurs as granular or massive aggregates of yellowish-black or brown color, featuring a characteristic submetallic luster. This structural component frequently appears in low-temperature hydrothermal veins associated with other complex sulfides or in contact-metamorphosed manganese deposits, being utilized as a petrological indicator in establishing precision mineral fusions.
