Posachedwa, mtolankhaniyo adaphunzira kuchokera ku Henan Provincial Bureau of Geology and mineral exploration kuti mchere watsopano udatchulidwa mwalamulo ndi International Association for mineral exploration and Development, ndipo idavomerezedwa ndi gulu latsopano la mineral.

Malinga ndi akatswiri a Bureau, mgodi wa siliva wa kongtizu unapezeka mu mgodi wa golide wa Yindongpo, Tongbai County, Nanyang City, Province la Henan.Ndi membala wachisanu ndi chinayi wa banja latsopano la mchere wapadziko lonse lapansi yemwe ndi wa "Henan nationality".Pambuyo pofufuza mwadongosolo mineralogical pazakuthupi, kapangidwe kake, mawonekedwe a kristalo ndi mawonekedwe owoneka bwino, gulu lofufuzira linatsimikizira kuti ndi mchere watsopano wa banja la tetrahedrite lomwe silinapezeke m'chilengedwe.

Malinga ndi kuwunika ndi kafukufuku, mchere wamchere wamchere ndi wotuwa wakuda, wotuwa pansi pa kuwala, ndipo uli ndi kuwala kofiira mkati, opaque zitsulo zonyezimira ndi mikwingwirima yakuda.Ndiwosasunthika ndipo imagwirizana kwambiri ndi mchere monga rasipiberi siliva ore, sphalerite, galena, tetrahedrite yachitsulo yopanda kanthu ndi pyrite.

Akuti chitsulo chopanda kanthu tetrahedrite ndiye mchere wolemera kwambiri wa siliva wa tetrahedrite m'chilengedwe, wokhala ndi siliva wa 52.3%.Chofunika kwambiri, mawonekedwe ake apadera amadziwika ngati chinsinsi chosasinthika cha banja la tetrahedrite ndi anzawo apadziko lonse lapansi.Kuchita kwake kwapadera mu catalysis, chemical sensing ndi photoelectric ntchito zakhala malo otentha kwambiri mu kafukufuku wamagulu asiliva.
