| Wollastonittmineraliseringen ligger i 750 m høyde i Nordhellinga til Nordvikfjell. I en 30 m bred kalk som ligger inne i granatkvartsglimmerskifrene i området har et 3 m bredt parti fått utviklet wollastonitt i 10 m lengde inn mot kontakten til en par meter tykk tonalittgang. Wollastonitten utgjør ca. 10% av kalken, og granatinnholdet er på ca 20%. |
