| Mellom hovedveien og en ny vei opp til et nytt boligfelt er det en skjæring med vegger på 3x2 m. Skjerpet er 1-1,5 m dypt. I veggen i vestsørvest finnes flere tynne, 2-10 cm, kvartsårer med blyglans. Ca. 3m lengre i samme retning finnes en 3 m lang og 2,5 m høy vegg med en liten gjengrodd grop som også kan være en del av skjerpet. Vertsbergarten er en felsisk amfibol-førende gneis som er foldet med dannelse av kvartsårene langs mindre skjærsoner langs akseplan. Årenes orientering er 220°/68°. Blyglans og mindre mengder kobberkis og pyritt danner smale striper langs kvartsårene og finnes disseminert i disse. |
