Et lite skjerpet ligger nær et jorde ved gården Dørdal på nordsida av E18. Det er utsprengt 1x2 m på vestsida av en mindre knaus. Vertsbergart er en kvarts-biotitt skifer med mange, få cm-tynne kvartsslirer. Skjerpet er anlagt i ombøyningen til en åpen, liggende fold med foldeakse 106°/0°. Svak sulfiddisseminasjon opptrer i en 20 cm bred sterkt rustfarga og noe serisittisert sone i skiferen (prøve .01). Pyritt er det viktigste sulfidmineralet. Mineraliseringen er ubetydelig og har ingen økonomisk interesse. |
