4. The material is usually described as V4+(S22-)2. Structurally, it is a "linear-chain" compound with alternating bonding and nonbonding contacts between the vanadium centers. The vanadium is octa-coordinated, which is an uncommon geometry for this metal.
The mineral was first described in 1906 for an occurrence in a vanadium mine near Mina Ragra, Junín, Cerro de Pasco
, Peru
. It was named for Peruvian metallurgist Antenor Rizo-Patron (1866–1948) the discoverer of the deposit. At the type loality
in Peru it occurs in fissures within a red shale likely derived from an asphaltum deposit. Associated minerals include, native sulfur, bravoite, pyrite
, minasragrite, stanleyite, dwornikite, quartz
and vanadium bearing lignite
. It has also been reported from the Yushkinite gorge on the Middle Silova-Yakha River on the Paikhoi Range of the polar Urals of Russia and from the Tsumeb
mine in Namibia

Vanadium
Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery gray, ductile and malleable transition metal. The formation of an oxide layer stabilizes the metal against oxidation. The element is found only in chemically combined form in nature...
sulfide mineral
Sulfide mineral
The sulfide minerals are a class of minerals containing sulfide as the major anion. Some sulfide minerals are economically important as metal ores. The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts...

Sulfur
Sulfur or sulphur is the chemical element with atomic number 16. In the periodic table it is represented by the symbol S. It is an abundant, multivalent non-metal. Under normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S8. Elemental sulfur is a bright yellow...

Pyrite
The mineral pyrite, or iron pyrite, is an iron sulfide with the formula FeS2. This mineral's metallic luster and pale-to-normal, brass-yellow hue have earned it the nickname fool's gold because of its resemblance to gold...

Quartz
Quartz is the second-most-abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO2. There are many different varieties of quartz,...
