f Multivariate statistical analyses of geophysical multi-method prospecting data as applied to geologic mapping

The simultaneous evaluation of multi-method geophysical observations - most profitable in geologic mapping and known as integrated or complex interpretation - has been usually performed manually. This man-made synopsis is laborious. Its result strongly depends on the skill and experience of the geophysicist. To obtain more objective and efficient results it was necessary to develop an automatic and quantitative procedure. It is based upon multivariate analysis methods which offer a promising approach to the integrated interpretation, as LANNE (1986) demonstrated. Our paper is thought to promote the use of multivariate analysis methods in applied geophysics.
