| Skjerpet ligger 2 m over havet på Fugløys sydøstlige hjørne og ses lett p.g.a. gabbroens rustrøde farge ved skjerpet. Skjerpet er ganske lite, det er utsprengt 3-4 m3. Mineraliseringen er linseformet, svakt deformert og har en utstrekning på ca. 5 m. Tykkelsen er i skjerpet 10-15 cm, orienteringen er ca. 160°/90°. I skjerpet opptrer malmen i cm-store klumper eller "veinlets" i den gabbroide bergarten. I skjerpets bakvegg ses en Ø-V-orientert og loddrett stående 30 cm tykk dolerittåre, den skjæres av en N-S-orientert og loddrett stående granittåre. Disse årer har sannsynligvis ingenting med mineraliseringen å gjøre. Mineraliseringen er sannsynligvis likvid-magmatisk. |
