Bratthagen 1, Hedrum, Larvik kommune, Vestfold fylke, Norge
Roadcut along RV 40 (former RV 8). The locality consists of several nepheline syenite pegmatites, usually 10-30 cm thick, often rather irregularly cross-cutting. Nearly 60 different mineral species have been found in the dikes. Because of its complex and scientifically interesting mineralogy, the locality has been protected by law since 1984.
