Nguva pfupi yadarika, mutori wenhau akadzidza kubva kuHenan Provincial Bureau yeGeology nekuongorora zvicherwa kuti chicherwa chitsva chakadanwa zviri pamutemo neInternational Association for mineral exploration and development, uye chakatenderwa neiyo itsva mineral classification.

Sekureva kwevanyanzvi veBureau, mugodhi wesirivha wekongtizu wakawanikwa mumugodhi wegoridhe weYindongpo, Tongbai County, Nanyang City, Henan Province. Iyo inhengo yepfumbamwe yemhuri nyowani yemaminerari yemhuri ye "Henan nyika". Mushure mekuita zvidzidzo zvemineralogical pamusoro pezvinhu zvemuviri, chimiro chemakemikari, chimiro chekristaro uye spectral maitiro, boka rekutsvagisa rakasimbisa kuti iminerari nyowani yemhuri yetetrahedrite isati yawanikwa mune zvakasikwa.

Zvinoenderana nekutarisa uye tsvagiridzo, iyo mineral sample igrey nhema, grey pasi pechiedza, uye ine brownish tsvuku yemukati ratidziro, opaque simbi inopenya uye mitema mitsetse. Iyo ine brittle uye padhuze inopindirana nemaminerari akadai secrimson sirivheri ore, sphalerite, galena, isina simbi simbi tetrahedrite uye pyrite.

Zvinonzi simbi isina chinhu tetrahedrite ndiyo yakawanda sirivha yakapfuma tetrahedrite mineral muzvisikwa, ine sirivheri ye52.3%. Zvinotonyanya kukosha, chimiro chayo chakakosha chinozivikanwa sechakavanzika chisina kugadziriswa chemhuri yetetrahedrite nevekunze vezera. Kuita kwayo kwakatanhamara mu catalysis, kemikari inonzwa uye mafotoelectric mabasa yave nzvimbo inopisa mumunda wekutsvagisa wemasumbu esirivha.
