Summary:The methods of data preparation, storage, retrieval and analysis are described, with particular reference to Bouguer anomaly and gravity maps of Britain north of the National Grid coordinate 550 km N. Details about stripping the gravity effect of the main sedimentary basins are given and there is a section concerned with comparison of gravity and topography. The very large negative Bouguer anomaly over the Central and Grampian Highlands is attributed to isostatic effects of high topography, two separate groups of stock-like Caledonian granites and a hitherto unsuspected density contrast between the Dalradian and Moine of approx 100 kg/m3 (0.1 g/cm3).
