Vanadium sulfide — a chain-structured vanadium mineral of the famous asphaltite-hosted vanadium deposits.
Intro adapted from Wikipedia (CC BY-SA).
Patrónite is an IMA-recognized mineral species in the sulfide class, with the chemical formula VS₄.
It crystallizes in the monoclinic crystal system (space group I2/c).
Key properties: specific gravity 2.82; Metallic luster.
IMA symbol Pat, IMA status: approved, named in 1906.
Occurs as interstitial filling in the core of a porous 2.5 m layer of admixed vanadium- bearing minerals. These vanadian materials are in fissures that cut red shales and that were probably filled by a remobilized asphaltite deposit.
It is found associated with Sulfur, bravoite, pyrite, minasragrite, stanleyite, dwornikite, quartz, vanadian lignite, natural coke.
The name commemorates Antenor Rizo-Patrón (1866–1948), Peruvian metallurgist, discoverer of the Peruvian occurrence.
