Among other things, he was also the first geologist to note the peculiar occurrence of native lead at Långban in 1871. The mineral name igelströmite has been used twice previously: first, as a synonym never given species status (and misspelled “ingelstromite”), for a colour variety of pyroaurite (Heddle, 1878), a mineral originally described by Igelström (1865) from Långban, and the second time by Weibull (1883) for an intermediate member of the tephroite–fayalite series with composition range 20 %–40 % Mn2SiO4, and thus it was never accepted as a separate species.","2025-08-11 12:15:23",[],[69,75,84,93],{"id":70,"name":71,"entrytype":9,"csystem":30,"ima_formula":72,"mindat_formula":72,"hmin":37,"hmax":38,"dmeas":11,"dcalc":73,"primary_image_id":74},470695,"Manganoschafarzikite","MnSb\u003Csub>2\u003C\u002Fsub>O\u003Csub>4\u003C\u002Fsub>","5.37",15358,{"id":76,"name":77,"entrytype":9,"csystem":30,"ima_formula":78,"mindat_formula":79,"hmin":80,"hmax":80,"dmeas":81,"dcalc":82,"primary_image_id":83},2721,"Minium","Pb\u003Csup>2+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>Pb\u003Csup>4+\u003C\u002Fsup>O\u003Csub>4\u003C\u002Fsub>","Pb\u003Csub>3\u003C\u002Fsub>O\u003Csub>4\u003C\u002Fsub>",2.5,"8.9","8.92",16325,{"id":85,"name":86,"entrytype":9,"csystem":30,"ima_formula":87,"mindat_formula":88,"hmin":89,"hmax":89,"dmeas":90,"dcalc":91,"primary_image_id":92},3554,"Schafarzikite","Fe\u003Csup>2+\u003C\u002Fsup>(Sb\u003Csup>3+\u003C\u002Fsup>)\u003Csub>2\u003C\u002Fsub>O\u003Csub>4\u003C\u002Fsub>","Fe\u003Csup>2+\u003C\u002Fsup>Sb\u003Csup>3+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>O\u003Csub>4\u003C\u002Fsub>",3.5,"4.3","5.24",21711,{"id":94,"name":95,"entrytype":9,"csystem":30,"ima_formula":96,"mindat_formula":96,"hmin":38,"hmax":38,"dmeas":97,"dcalc":98,"primary_image_id":99},4023,"Trippkeite","Cu\u003Csup>2+\u003C\u002Fsup>As\u003Csup>3+\u003C\u002Fsup>\u003Csub>2\u003C\u002Fsub>O\u003Csub>4\u003C\u002Fsub>","4.8","4.49",24544,[],[],[103],{"id":104,"txt":105,"latitude":106,"longitude":107,"country":108},3167,"Långban Mine, Långban Ore District, Filipstad, Värmland County, Sweden",59.8553767,14.2648029,"Sweden",[110,115,119],{"id":111,"year":112,"html":113,"doi":114},16143440,2021,"Miyawaki, Ritsuro, Hatert, Frédéric, Pasero, Marco, Mills, Stuart J.
