| Grå grovkornet båndet kalkstein, kraftig foldet med grafitt i elongerte aggregater parallell med foliasjonen. Overalt impregnert av svovelkiskrystaller. I partier er den meget urein med høyt innhold av silikater og med glimmer som det mest fremtredende silikatmineralet. Av andre fremtredende silikater kan nevnes kvarts og feltspat. Foliasjon er tilnærmet Ø - V med fall på ca. 50° mot syd. Heng's bergarten er glimmergneis. Prøve merket Ø 98 - 4. |
