Abstract:
Norges geologiske undersøkelse mottok i jan.79 en henvendelse fra Industridepartementet om å gi en samlet, kortfattet oversikt over Norges skiferforekomster. Alt materiale er tatt fra rapporter ved bergarkivet, NGU og de mest relevante opplysninger er samlet i vedlagte bilag. Bilagene er ordnet fylkesvis. Hver lokalitet er angitt med plottnr. som igjen refererer til vedlagte kart.
