Gravity and magnetic anomaly map pack: North sheet (1:625 000) [Map Pack]
Price £15.00(no VAT)
Gravity and magnetic anomalies show small departures from the expected values of the earth's gravity and magnetic fields, caused by variations in the density and magnetisation of the rocks within the crust. These anomalies are used to determine concealed geological structure, including the depth and extent of sedimentary basins, depth to magnetic basement and location of concealed igneous bodies. On the broadest scale, they help to convey an understanding of the regional configuration of the Earth's crust and upper mantle.
This map pack contains two geophysical maps covering the northern part of the UK landmass (England north of the Lake District, Scotland, Northern Ireland and the Isle of Man), at 1:625 000 scale. Also shown are the adjacent sea areas. The gravity map shows contour values as Bouger anomaly onshore and free-air anomaly offshore. The magnetic map shows countours displayed as total field anomaly.
The map pack contains a folded North Gravity anomaly map and a folded North Magnetic anomaly map in a clear plastic wallet. [Map Pack]
