1 Gravity Anomaly Maps pack (UTM series) 1:1 000 000 [Map Pack]

While ‘standard’ geological mapping describes the surface and near-surface rocks and structures, geophysical techniques are needed to look deeper and describe the substructure. Variations in the density of rocks have an effect on the local strength of the Earth’s gravity field, and these gravity anomalies can be mapped to aid understanding of geological structures at depth. These Gravity Anomaly maps offer insights into the three-dimensional structure of the country that will be of interest to the earth science community, particularly those involved in onshore hydrocarbon and mineral exploration. …more…

2 Gravity and magnetic anomaly map pack: North sheet (1:625 000) [Map Pack]

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. …more…
