Lossenite
Lossenite is the name that is no longer used today for a mineral mixture of scorodite and beudantite . It was named in 1894 by Ludwig Milch after the German geologist Karl August Lossen , who presented the first geognostic map of the Harz in 1877 and who dealt with the geology of the Harz for a long time .

Even Friedrich Klockmann described Lossenit 1903 as a mineral , which for the first time in Lavrion ( Laurion , Attica was discovered, Greece) and rhombic -pyramidalen, the Skorodit similar, small crystals occurred. Lossenite is, according to Klockmann, a brownish-red and superficially rusty weathered, water- and SO 2 -containing arsenate of iron and lead.
Alfred Lacroix also found scorodite in paragenesis with beudantite at Lavrio in 1915 and assumed that the original description was based on the investigation of a mechanical mixture of the two minerals, which was confirmed by renewed investigations on the type material from Lavrio. Lossenite has therefore been discredited as an independent mineral since 1950.
