| Description |
| Bergarten er grønn fyllitt som har blitt formatert til takskifer. Forekomsten ligger i samme skifersone som Hastad (nr. 1714616) som ligger 6-700 m lenger øst, og bergarten er lik i de to forekomstene. Bruddet dekker et areal på ca. 20x20 m, det tilsier at produksjonen herfra har vært ganske liten. |
| Location |
| Bruddet ligger i en liten bekkdal 3-400 m øst for gården Svartåsen. Det ligger sør for bekken, og i tillegg er det brutt litt skifer også like nord for bekken. |
