The use of geophysical images in subsurface investigations of the Solway Basin, England.

This paper focuses on the use of low-cost geophysical data sets in raster format for structural analysis of a small onshore basin in NW England. Gravity and aeromagnetic data are expressed as images enhanced by a variety of image-processing methods, aimed at expressing the data in a form most readily appreciated by human vision. This involves side-illumination of the data using directional first derivative filters and pseudo-colouring based on look-up table techniques. The principal data handling method was trend-surface analysis and calculation of nth-order residual images. Most of the known structural attributes of the basin are resolved, together with previously unknown features affecting the basin's deep architecture.
