In the course of field work during the summer of 1963, well-preserved pillow lavas were found in the Caledonian of the Grong district. Due to road-work, ice-scoured outcrops north of Solberg farm had been cleared of their moraine cover. Although no detailed mapping was carried out, exposures with pillow lava structures could be followed for at least 1 km along the road to the northeast where they are associated with more coarse-grained gabbroic rocks. At the road junction west of Solberg, fragmental rocks, apparently of pyroclastic origin, can be seen.
