N2 - In Finland three crystalline rock sites (Romuvaara, Kivetty and Olkiluoto) have been selected for detailed site investigations of Teollisuuden Voima Oy (TVO) for the disposal of the high level waste. The objective of the work has been to study the possibilities of applying the principal component analysis (PCA) of single borehole data to the identification and classification of hydrogeologically important fracture zones. The fracture zone index (FZI) is defined as the first principal component of data from the hydraulic conductivity of 31 m tests, resistivity loggings, radar reflections, open and filled fracture observations and gamma-gamma density/P-wave velocity loggings. FZI anomalies have been compared against earlier conceptualizations based on the overall expert opinion of geological, geophysical and geohydrological information.
