Description :
The granite area of Bohuslän is characterised by an abundance of rock basins of different sizes. These basins were measured, described and classified from air-photos according to their length, width, area, altitude, shape, boundaries, openness and relation to joint configuration. The depth of basins was collected from digital elevation data. The patterns and characteristics of the bassins suggest that deep selective weathering had been the primary process involved in the origin and evolution of the basins. The AA. also aim to discriminate between glacial and non-glacial component in rock basin development and to demonstrate the degree of rock control upon morphology in the formerly glaciated area.
