Wolframite from
Monroe, Fairfield County, Connecticut, USA

Species:'Wolframite' (not an IMA approved species)
Formula:(Fe2+)WO4 to (Mn2+)WO4
Comments:Original descriptions by Silliman (1819a, 1819b, 1819c) match the pseudomorphs of ferberite after scheelite unique to Lane's Mine of Trumbull (not Monroe), both places worked at the time by Ephraim Lane. Samples were sold and shipped to Silliman, he did not collect them. Origin was eventually cleared up by Hitchcock and Silliman (1826).
Validity:Erroneously Reported
References:Silliman (1819a, 1819b, 1819c); Hitchcock and Silliman (1826)
