The Palaeoproterozoic Kristineberg area in northern Sweden comprises five sulphide mineralizations occurring within a regional-scale, fault-controlled antiformal structure. The ~E-W faults show reverse shear senses with the largest dip-slip displacements in the east. However, based on both the steep orientations of the faults, as well as their close relationship with intense folding on the above metavolcanic rocks, the faults are considered to have their origin in a phase of crustal extension pre-dating compressional deformation. The SW-NE crustal shortening was regionally partitioned into both ~E-W and ~N-S trending high-strain structural domains, whereas the Kristineberg mine vicinity shows a pattern of sub-horizontal stretching with top-to-the-E kinematics and S-block-up reverse faulting. The above features together formed the Kristineberg deposit into its present shape with steep planar bodies close to the surface and elongate, gently W-plunging bodies indicating intense stretching at depth.
