(a) Bedrock map after Wahlgren et al. [32] of the Laxemar area outlining borehole locations and fracture lineaments (also indicated are villages and roads). Thick black lines indicate underground extension of inclined drill cores. KLX04 is vertical while KLX08 stretches to SW. (b) Regional map of south Sweden indicating the location of the Transscandinavian Igneous Belt (TIB) in grey shade and the Laxemar area with arrow. (c) Geological model adapted from Cruden [21] of the Götemar granite across a N-S trending profile stretching beyond the map in a northerly direction, with the relative location of drill cores KLX06 and KLX09 indicated. At least one sample from each drill core outlined in the map has been used in this study.
