The geometry and emplacement of conical sandstone intrusions

Journal article

Conical sandstone intrusions with a geometry comparable with that of many igneous sills have been identified using 3D seismic data from large areas of the North Sea and Faeroe-Shetland Basins. These intrusions are of reservoir scale, ranging from 100 to 2000 m or so in diameter, 50-300 m in height, and 1-80 m in thickness (aperture). They are concentrated in specific stratigraphic intervals in the Cenozoic fills of both basins. Two geometrical end members are recognised and defined here: 'api...
