In essence, Fanfani and Zanazzi (1967) had discovered a new mineral species (ferroberaunite) but re-used a previous name. In the 19th century, both beraunite and eleonorite had been applied to the fully oxidized mineral. Eleonorite had been re-applied by the IMA to the oxidized end-member of the beraunite-eleonorite series. In the IMA 21-D redefinition the name beraunite, based on a restudy of the type material, was reapplied to the oxidised phase (Vrtiška et al., 2022) and the name ferroberaunite was created for the mixed-valence phase (Tvrdý et al., 2021).","2026-04-09 18:08:50",[],[84,92,99],{"id":85,"name":86,"entrytype":9,"csystem":30,"ima_formula":87,"mindat_formula":88,"hmin":38,"hmax":41,"dmeas":89,"dcalc":90,"primary_image_id":91},628,"Beraunite","Fe\u003Csup>3+\u003C\u002Fsup>\u003Csub>6\u003C\u002Fsub>(PO\u003Csub>4\u003C\u002Fsub>)\u003Csub>4\u003C\u002Fsub>O(OH)\u003Csub>4\u003C\u002Fsub> · 6H\u003Csub>2\u003C\u002Fsub>O","Fe\u003Csup>3+\u003C\u002Fsup>\u003Csub>6\u003C\u002Fsub>(PO\u003Csub>4\u003C\u002Fsub>)\u003Csub>4\u003C\u002Fsub>O(OH)\u003Csub>4\u003C\u002Fsub>·6H\u003Csub>2\u003C\u002Fsub>O","2.8","2.894",3076,{"id":93,"name":94,"entrytype":9,"csystem":30,"ima_formula":95,"mindat_formula":96,"hmin":38,"hmax":41,"dmeas":11,"dcalc":97,"primary_image_id":98},46532,"Tvrdýite","Fe\u003Csup>2+\u003C\u002Fsup>Fe\u003Csup>3+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>Al\u003Csub>3\u003C\u002Fsub>(PO\u003Csub>4\u003C\u002Fsub>)\u003Csub>4\u003C\u002Fsub>(OH)\u003Csub>5\u003C\u002Fsub>(H\u003Csub>2\u003C\u002Fsub>O)\u003Csub>4\u003C\u002Fsub> · 2H\u003Csub>2\u003C\u002Fsub>O","Fe\u003Csup>2+\u003C\u002Fsup>Fe\u003Csup>3+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>Al\u003Csub>3\u003C\u002Fsub>(PO\u003Csub>4\u003C\u002Fsub>)\u003Csub>4\u003C\u002Fsub>(OH)\u003Csub>5\u003C\u002Fsub>(H\u003Csub>2\u003C\u002Fsub>O)\u003Csub>4\u003C\u002Fsub>·2H\u003Csub>2\u003C\u002Fsub>O","2.834",24808,{"id":100,"name":101,"entrytype":9,"csystem":30,"ima_formula":102,"mindat_formula":103,"hmin":11,"hmax":11,"dmeas":11,"dcalc":104,"primary_image_id":105},47608,"Zincoberaunite","ZnFe\u003Csup>3+\u003C\u002Fsup>\u003Csub>5\u003C\u002Fsub>(PO\u003Csub>4\u003C\u002Fsub>)\u003Csub>4\u003C\u002Fsub>(OH)\u003Csub>5\u003C\u002Fsub> · 6H\u003Csub>2\u003C\u002Fsub>O","ZnFe\u003Csup>3+\u003C\u002Fsup>\u003Csub>5\u003C\u002Fsub>(PO\u003Csub>4\u003C\u002Fsub>)\u003Csub>4\u003C\u002Fsub>(OH)\u003Csub>5\u003C\u002Fsub>·6H\u003Csub>2\u003C\u002Fsub>O","2.92",22629,[],[],[109],{"id":110,"txt":111,"latitude":112,"longitude":113,"country":114},1118,"Gravel Hill Mine (Cliff Iron Mine; Penhale Iron Mine), Perran Iron Lode (Great Perran Iron Lode), Perranzabuloe, Cornwall, England, UK",50.3741667,-5.145,"UK",30,[117,121,125,129,133,137,141,145,150,154,158,162,166,171,175,179,184,188,193,197,201,205],{"id":118,"year":119,"html":120,"doi":11},16102792,1840,"Breithaupt, A.
