| Description |
| Bergarten er en meget grovkornet, svakt rødlig granitt. Bruddet er lite, området hvor det brudt ut granitt er 10-15 m bredt langs veien og omtrent samme dimensjon motsatt vei. Det er ikke gått vesentlig i dybden,- terrengoverflata er bare litt lavere i bruddet enn på sidene. |
| Examples |
| Steinen er nevnt brukt til kai i Kristiansand og til gravsteiner. |
| Location |
| For å komme til Spetteland kjører man fra Mandal på vestsiden av Mandalselva ca. 4 km. Veien til Spetteland tar her av til venstre. Bruddet ligger på N-siden av veien 3-400 m Ø for gårdene på Spetteland. |
