Geostatistics, ordinary kriging, spatial estimation and contouring
Abstract
Until very time ago Geology was frequently considered a science based on purely qualitative interpretations of the geological phenomena. In the last 40 years, however, occurred a notable change from the descriptive phase to utilization of quantitative methods, mostly in the Applied Geology area. Among many related subjects to the quantification in Geology the boarded one in this paper concern the application of Geostatistics in geological mapping. In the first part of the article is introduced quantitative aspects in the interpretation of the geological phenomena, soon after basic concepts concerning geostatistical methodology and, finally, a classical application of lineal geostatistics, based on covariance and variogram stationary concepts, for spatial estimation and contouring.
