Cattierite

Cattierite (CoS2) is a <a href="/facts/Cobalt/gqhScEw4">cobalt</a> <a href="/facts/Sulfide_mineral/f8rxJpCW">sulfide mineral</a> found in the <a href="/facts/Democratic_Republic_of_Congo/E2KmHDdv">Democratic Republic of Congo</a>. It was discovered together with the <a href="/facts/Nickel_sulfide/2UWCgMew">nickel sulfide</a> <a href="/facts/Vaesite/DjhA75Pq">vaesite</a> by <a href="/facts/Johannes_F._Vaes/IRvgnVXd">Johannes F. Vaes</a>, a Belgian mineralogist and named after Felicien Cattier, who was chairman of the board of the <a href="/facts/Union_Mini%C3%A8re_du_Haut-Katanga/UVGBJaVo">Union Minière du Haut-Katanga</a>.
The mineral belongs to the <a href="/facts/Pyrite_group/hoPHxVue">pyrite group</a>, in which all minerals share the same building principle. The metal in the oxidation state +2 forms a <a href="/facts/Sodium_chloride/MWcXl3Mb">sodium chloride</a> structure together with the anion S22−. This formalism recognizes that the sulfur atoms in pyrite occur in pairs with clear S-S bonds.
It occurs with <a href="/facts/Pyrite/41CYREyr">pyrite</a>, <a href="/facts/Chalcopyrite/MXBDffGw">chalcopyrite</a> and members of the <a href="/facts/Linnaeite/er1q6F3d">linnaeite</a> – <a href="/facts/Polydymite/7rrffvKf">polydymite</a> group in ore deposits in <a href="/facts/Carbonate_rock/pKYTxRkM">carbonate rocks</a>. In addition to the type locality in the Katanga district it is reported from Gansberg, <a href="/facts/Black_Forest/bbXsJTp4">Black Forest</a>, Germany; near <a href="/facts/Filipstad/Wa0GtBIh">Filipstad</a>, <a href="/facts/Varmland/enbV17Ql">Varmland</a>, Sweden; Bald Knob, near <a href="/facts/Sparta/6V9o1DSz">Sparta</a>, <a href="/facts/Alleghany_County,_North_Carolina/Ka3SzQbM">Alleghany County, North Carolina</a> and in the Fletcher mine of <a href="/facts/Reynolds_County,_Missouri/19vpEWuT">Reynolds County, Missouri</a>.
