| Skjerpet er en 5 m lang røskegrøft på tvers av strøket, i liten skrent 20 m øst for Blisterbekken. Grøfta er ca. 1.5 m bred og ca. 1.5 m dyp. Mineralisering består av en svak, båndvis anrikning i impregnasjon av pyritt i vekslende kvarts-kloritt- og kvarts-sericittskifer med noe kloritt. Pyritt opptrer i stor grad i subhedrale til euhedrale kuber med kornstørrelse 1-10 mm. Denne mineraliseringen er også blottlagt i Blisterbekken. Sidebergart er amfibolitt, dels finkornet massiv, dels skifrig og klorittrik. |
