Aims of these investigations; 1) mapping of soil thicknesses and composition, 2) locating conductive structures in bedrock, 3) studies of P-wave velocity anisotropy. Interpretation of seismic velocities indicates three layers in the overburden; 1) loosely packed sand, P-wave velocity: 300-700 m\/s, 2) loosely packed till, P-wave velocity: 1000-1500 m\/s, 3) compact till, P-wave velocity: 1900-2200 m\/s. The overburden thickness is in the range 0-30 meters. Slingram measurements have delineated conductive zones in more detail than previous electrical profiling (MISC). Electrical measurements are more sensitive to structures with low conductivity than slingram measurements. A correlation between high conductivity and low P-wave velocity in bedrock is indicated. This is probably due to fracturing. There is an indication of slightly higher P-wave velocity along the bedrock strike direction than across (anisotropy). 30326 Report kola peninsula NGU Open Archive (Geological Survey of Norway) Kola Peninsula Lotta ENVELOPE(30.700,30.700,68.700,68.700) Norway |
