Electrical and Slingram profiling is carried out in the border area between Norway and Russia. The aim of this survey was to map near outcropping conducting structures in the ground, and to see how these two methods worked together on this problem. Magnetic profiling was performed to help in the interpretation. Two profiles on the norwegian side and two profiles on the russian side of the border were examined. Data from the profiles on the norwegian side are presented in this report. Based on electrical profiling, detailed resistivity cross sections are constructed. Electrical profiling by the MISC method is effective for 2D mapping of rocks in a wide range of electrical resistivity. The Slingram method is less sensitive at low conductivity, but gives complementary information at moderate and high conductivity.
