| På Brattåsen, i krattkledt terreng, er det gjort røsking på kismineralisering knyttet til kvartsitt med grafittholdige bånd og med amfibolittbånd. Mineraliseringen består av semimassiv magnetkis med hyppige grafittslirer, tilgrenset av svak disseminasjon. Total mineraliseringsmektighet i røskene er ca. 1.5 m. |
