Program

• Mass balances and volume changes occurring in a wide variety of geologic internal and supergenic processes. Classic and normalized methods. Arithmetic and graphical resolutions.


• Multivariate analysis applied to the prospecting of multiple spatial data series. Data and results mapping. Calculation of residuals. Normalizing and ‘standardizing’ the data. Superposed anomalies and influence of penalizing elements. ‘Boolean maps of anomalies’.


• Extraction of colorimetric data from raster images of geological and topographic maps. The ‘MagicMap’ application.


• Conversion and calibration of geological and topographic vector maps from their raster equivalents.


• Data digitalizing from geological and topographic maps and from science books and magazines: the ‘Engauge digitizer’.


• Basic principles of photogrammetry. Use in the joint and fault spacing and continuity measurement.


• Structural data manipulation: rose diagrams, stereograms, spherical statistics, fracture densities, fracture intersection densities and fracture total length.
