| Forekomsten ligger 3-4 km øst for Steinkjer i Egge. Kalksteinen ligger i en ØNØ-VSV-gående ås. Kalksteinsformasjonen er splittet av et 25-30 m mektig skiferlag. Mektigheten på formasjonen er anslått til ca. 80 m. Kalksteinen er hvit til blek gul og grovkornet. Tonnasje: 4 mill. tonn i dagbrudd (Poulsen 1944). Bebyggelse gjør at forekomsten har liten økonomisk interesse i dag (2003). |
