Geophysical characteristics of precambrian fracture zones - A case study from Rovaniemi, Northern Finland

The recognizing of fracture zones is important in the geological mapping, ore prospecting, ground water studies and in the applications of rock engineering. In environmental accidents fracture zones may also provide flow channels for groundwater contaminants. The aim of this study is to locate and characterize potential bedrock aquifers. The study is methodical and it is continuation of earlier works (Lanne et al., 1998).
