3D geological models based on data fromgeological field observations, magnetic airborne surveys and combined XRF-XRT scanning of drill core arepresented for the Lovisa-Håkansboda and the Stråssa-Blanka mineral systems (1.9 - 1.8 Ga). At first, the 3D architecture of several deposits was derived primarilyfrom surface data and mine-level maps. Secondly, geochemical and structural constrains from drill corescanning (XRF-XRT) were used to refine the modelslocally to a detailed, in-mine scale. The constructed models were then placed in a regional context providingvaluable insight on the area’s local and regional deformation pattern. All modelled deposits are plunging 50-60° towards the south-southeast reflecting D2 deformation (vertical shearing) during NW-SE-directed shortening and are locally overprinted by D3 (lateral shearing) during N-S-directed shortening.
