Summary
Under the auspices of Nordlandsprogrammet, several initiatives have been taken to locate areas where natural conditions are present to establish large coastal aggregate plants. The investigations have been undertaken as a co-opertive project between industrial partners, the Nordland County Authority and NGU. This report is a compilation of investigations carried out previously. As the demands vary with regard to both how the material will be used and the European country concerned, it is difficult to make a common evaluation of the quality of the rock. As an overall assessment, the quality is considered to be poor for Råna, Kilheia, Velsvåg and Ursfjorden and very poor for Øyrfjellet in relation to the quality demands stipulated for building raw materials in England, Germany, France, the Netherlands, Belgium and Norway. The analysis results show that the material from Øyrfjellet in Gildeskål is too poor to be used as building raw material. The rock quality for the samples taken in the other areas is on the borderline of what should be accepted as fulfilling the minimum demands for the establishment of large aggregate plants aimed at the export market in Europe. The material is entirely suitable for delivery to the "offshore market" to support and cover pipelines and other installations. For export to the USA, the quality of the material is adequate for use of road construction purposes, according to the information that is available regarding stipulated quality demands.
