bronita
Bronita is the name given in some speculative geology and science fiction to a hypothetical mineral. It is not currently recognized as a valid mineral species by leading databases or by the International Mineralogical Association. In the literature where bronita appears, it is typically described as a bronze-to-brown, metallic mineral with a conchoidal to uneven fracture and a metallic to submetallic luster. Reported appearances vary, with most accounts suggesting a relatively high density and a Mohs hardness in the mid-5 range; compositions proposed range from iron- and nickel-rich sulfide-like forms to oxide- and silicate-rich assemblages.
Occurrence and formation: Bronita is said to form under high-temperature metamorphic conditions or in ultramafic rocks,
Nomenclature and status: The name bronita derives from bronze-like coloration and follows common mineral-name conventions. As
Uses and cultural presence: In fiction, bronita may be depicted as an energy-intensive material, a gemstone
