structural geology The Skellefte mining District is located in northern Sweden and comprises Palaeoproterozoic, metamorphosed, supracrustal rocks and associated intrusive rocks, which are all host to several ore deposits. Modelling was performed in the GoCAD software platform, using structural geology and petrology as well as magnetic, gravity, seismic, electric and electromagnetic geophysical data, in order to produce robust 3-dimensional models for the upper 3000 m of the Earth's crust in selected areas within the Skellefte District. Further interpretations from the regional structures and tectonics are providing a base for restoring the geological history of the district in time, the 4th dimension.
