Sažetak
One of the initial steps for the building of a proper subsurface model for the basin analysis, after solving structural relations, is the determination of lithofacies distribution. This can be either performed as a general mixed lithology based on well logdata from a large interval or with a properly-layered model. In the latter, a variogram analysis has to be first employed to determine the spatial relation of lithofacies distribution for each mapped interval. Thus, variogram analysis was performed on five lithostratigraphic intervals in the eastern part of Drava Depression. The analysis was performed on four models of different geometry (cell size and layer number) with the same geographic and stratigraphic extent. Results of variogram analysis mainly donot show significant differences. In most cases, analysis shows that the major direction of variograms is similar as the “Dinaric” orientation in relation to the paleotransport direction. Some variograms show different orientation regarding stratigraphiclevel which could be interpreted to the regional shift in the depositional environments and sediment transport. Four lithofacies models were built upon the results of the variogram analysis which describe the spatial relation of each lithofacies.
