The ferrous iron analogue of manganilvaite.","For \"Ilva\", the old latin name of Elba Island, on which the co-type localites are situated.\r\nThe history of the name of ilvaite is complex. \r\nThe mineral was probably first observed in 1784 by the french geologist Déodat de Dolomieu (1750-1801) during his voyage to the Elba Island, Italy. According to Thiébaut de Berneaud (1808), it was found at Cap Calamita [\"\u003Cem>C'est à la punta della Calamita que Dolomieu trouva cette substance minèrale qu'on a depuis nommée yénite\u003C\u002Fem>\"]. As the mineral collected by Dolomieu didn't show crystal forms, he was induced to classify it as black schorl. The french mineralogist Romé de l’Isle (1736-1790) also had a crystal of the mineral in collection, labelled as \u003Cem>Mine de fer noirâtre attirable à l`aimant\u003C\u002Fem> [an iron mineral that is attracted by magnet] and originating from Rio Marina (Leliévre 1807, Thiébaut de Berneaud 1808, Schubnel 1999). In 1796, the French Mineralogist Louis-Benjamin Fleuriau de Bellevu (1761-1852) also collected the mineral at Cap Calamite (Leliévre 1807 (footnote p. 72-73), Schubnel 1999). It was analyzed by the french chemist Vaquelin. \r\n\r\nBut it was first published, described and named in 1807 by the French mineralogist Claude-Hugues Leliévre (28 june 1752, Paris, France -18 october 1835). He named it as \u003Cem>yenite\u003C\u002Fem>, in memory of the battle at Jena (in todays Germany) 14 October 1806. The battle was between the forces of Napoleon I of France and Frederick William III of Prussia.\r\nThe name should have been written Jenite, but according to Leliévre he changed it to Yenite, to avoid confusions with the prononciation. \r\n\r\nThe name was however criticized in the science community. Information on the new mineral was published by french geologist Jean-François D'Aubuisson in the German \u003Cem>Journal für die Chemie und Physik\u003C\u002Fem> in 1807. The author gave here another origin for the name: \"Le Lièvre gave it the name jenite in memory of the Mineralogical Society of Jena, of which he is member\" (It seems to be an attempt to soften a name unpleasent to all German).\r\n\r\nLater the German\u002FDanish-Norwegian philosopher and mineralogist Henrik Steffens (2 May 1773 Stavanger, Denmark-Norway - 13 February 1845 Berlin, Germany) in his \u003Cem>Vollständiges Handbuch der Oryktgnosie\u003C\u002Fem> (1811) introduced the name Ilvaite. \r\nLater, in 1812 another German, Abraham Gottlob Werner (in Hoffmann 1812, \u003Cem>Handbuch der Mineralogie\u003C\u002Fem> II, p. 376) proposed the name \u003Cem>Lievrite\u003C\u002Fem> in honor of Leliévre who first described the mineral.\r\nThe name Ilvaite is the name used today.\r\n\r\nLeliévre (1807), in his description, states that he found the mineral in two different localities on the Elba Island: At Rio Marina and at Cap Calamite.","2025-12-19 17:44:28",[],[93,100,107,114,122,131,137],{"id":94,"name":95,"entrytype":9,"csystem":96,"ima_formula":97,"mindat_formula":98,"hmin":49,"hmax":49,"dmeas":11,"dcalc":99,"primary_image_id":11},53234,"Amamoorite","Monoclinic","CaMn\u003Csup>2+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>Mn\u003Csup>3+\u003C\u002Fsup>(Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>)O(OH)"," CaMn\u003Csup>2+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>Mn\u003Csup>3+\u003C\u002Fsup>(Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>)O(OH)","3.88",{"id":101,"name":102,"entrytype":9,"csystem":38,"ima_formula":103,"mindat_formula":104,"hmin":11,"hmax":11,"dmeas":11,"dcalc":105,"primary_image_id":106},46165,"Cortesognoite","CaV\u003Csub>2\u003C\u002Fsub>Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>(OH)\u003Csub>2\u003C\u002Fsub> · H\u003Csub>2\u003C\u002Fsub>O","CaV\u003Csub>2\u003C\u002Fsub>(Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>)(OH)\u003Csub>2\u003C\u002Fsub>·H\u003Csub>2\u003C\u002Fsub>O","3.44",6344,{"id":108,"name":109,"entrytype":9,"csystem":38,"ima_formula":110,"mindat_formula":111,"hmin":44,"hmax":44,"dmeas":40,"dcalc":112,"primary_image_id":113},1867,"Hennomartinite","SrMn\u003Csup>3+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>(Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>)(OH)\u003Csub>2\u003C\u002Fsub> · H\u003Csub>2\u003C\u002Fsub>O","SrMn\u003Csup>3+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>(Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>)(OH)\u003Csub>2\u003C\u002Fsub>·H\u003Csub>2\u003C\u002Fsub>O","3.68",11155,{"id":115,"name":116,"entrytype":9,"csystem":38,"ima_formula":117,"mindat_formula":118,"hmin":119,"hmax":48,"dmeas":40,"dcalc":120,"primary_image_id":121},7116,"Itoigawaite","SrAl\u003Csub>2\u003C\u002Fsub>Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>(OH)\u003Csub>2\u003C\u002Fsub> · H\u003Csub>2\u003C\u002Fsub>O","SrAl\u003Csub>2\u003C\u002Fsub>(Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>)(OH)\u003Csub>2\u003C\u002Fsub>·H\u003Csub>2\u003C\u002Fsub>O",5,"3.37",12384,{"id":123,"name":124,"entrytype":9,"csystem":38,"ima_formula":125,"mindat_formula":126,"hmin":127,"hmax":127,"dmeas":128,"dcalc":129,"primary_image_id":130},2353,"Lawsonite","CaAl\u003Csub>2\u003C\u002Fsub>(Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>)(OH)\u003Csub>2\u003C\u002Fsub> · H\u003Csub>2\u003C\u002Fsub>O","CaAl\u003Csub>2\u003C\u002Fsub>(Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>)(OH)\u003Csub>2\u003C\u002Fsub>·H\u003Csub>2\u003C\u002Fsub>O",7.5,"3.1","3.09",14142,{"id":132,"name":133,"entrytype":9,"csystem":96,"ima_formula":134,"mindat_formula":134,"hmin":48,"hmax":49,"dmeas":135,"dcalc":136,"primary_image_id":11},26363,"Manganilvaite","CaFe\u003Csup>2+\u003C\u002Fsup>Fe\u003Csup>3+\u003C\u002Fsup>Mn\u003Csup>2+\u003C\u002Fsup>(Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>)O(OH)","3.92","3.93",{"id":138,"name":139,"entrytype":9,"csystem":38,"ima_formula":140,"mindat_formula":141,"hmin":44,"hmax":44,"dmeas":40,"dcalc":142,"primary_image_id":11},2923,"Noelbensonite","BaMn\u003Csup>3+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>(OH)\u003Csub>2\u003C\u002Fsub> · H\u003Csub>2\u003C\u002Fsub>O","BaMn\u003Csup>3+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>(Si\u003Csub>2\u003C\u002Fsub>O\u003Csub>7\u003C\u002Fsub>)(OH)\u003Csub>2\u003C\u002Fsub>·H\u003Csub>2\u003C\u002Fsub>O","3.87",[],[],[146,152],{"id":147,"txt":148,"latitude":149,"longitude":150,"country":151},2153,"Torre di Rio -
