Over the past two hundred years, the numerous and varied structural features of southern Britain have been mapped on the basis of outcrop information. Until relatively recently, the detailed nature of these structures at depth has remained conjectural. …more…

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…

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…

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 magnetisation of rocks within the Earth's crust can be mapped and these magnetic anomalies aid interpretation of buried geological structures, especially igneous and metamorphic bodies – vital in the search for minerals. These Magnetic Anomaly maps offer insights into the three-dimensional structure of the country that will be of interest to the earth science community, including those involved in onshore hydrocarbon and mineral exploration. …more…

While 'standard' geological mapping techniques describe the surface and near-surface rocks, geophysical techniques are needed to look deeper.
This interactive guide covers Northern Scotland, where the geophysical data provides insights into the components of the basement rocks, which were originally part of widely separated continents. Data on younger intrusive and sedimentary bodies is also provided. …more…
