Båndet magnetittmalm forekommer blottet like SV for Kovannet og nær østenden av Lamarksvannet. Malmen er tilknyttet mafiske granulitter, amfibolitter, kalkstein, diopsidiske bergarter og serpentinitter. Begge steder er malmmektigheten ca. 1m og båndingen består av vekslende lag magnetitt og olivin/serpentin. |
