Molypdeenmolybdeeni

Molypdeenmolybdeeni is a hypothetical mineral species introduced in mineralogical discussions as a molybdenum-rich oxide–sulfide phase. The name blends molybdenum with the suffix -eni, a convention used in some mineral-nomenclature examples to indicate a discrete mineral entity.

Proposed composition places molybdenum as the dominant element, with sulfur and oxygen as major anions, and minor amounts of trace elements such as copper and nickel. Empirically described as Mo_xS_yO_z, the exact stoichiometry is thought to vary with formation conditions. Crystallography is described as tetragonal to monoclinic, and the mineral is reported to have a metallic luster and a steel-gray to black appearance.

According to the fictional scenario, molypdeenmolybdeeni occurs in hydrothermal veins cutting granitic rocks and is spatially associated with molybdenite and other sulfide minerals. The type locality is described as the Espera mining district in a fictional mountainous region.

Physical properties are given as Mohs hardness 5–6 and a calculated specific gravity around 6.5–7.0. The mineral is reported as opaque with a bright to dull metallic streak and limited cleavage.

As of now, molypdeenmolybdeeni is not recognized by the International Mineralogical Association and remains a hypothetical example used to illustrate mineral naming and classification concepts.
