Denne forekomsten ligger rett bak den nedlagte skytebanen på vestsiden av myra. Hoved-delen av forekomsten består av en 30 m lang grøft i NNØ retning (325 grader). Grøfta er opptil 3-3.5 m dyp og inntil 1 m dyp. Den faller om lag 70-75 grader mot SV. 10-15 m sør for denne grøfta er det en 10 m lang grunnere grøft i mer N-S retning (340 grader). Den er inntil 1.5 m dyp og 1 m bred. Mineraliseringen i forekomsten består dels av tynne, rene magnetittårer i granitt og dels av kvarts-magnetittårer med epidot som gjennomsetter en tidligere amfibolomvandling rundt tidlige årer. Det er også en del årer med kalsitt som er omgitt av diopsid/hedenbergitt. |
