Abstract
A modeling strategy especially for big stratiform deposits was tested which combines an only partly computed model data base, with a set of transformation procedures. It is based on a set of n+2 two-dimensional models of every seam or layer, represented by digital maps or matrices. Thereby is n the number of parameters, describing the corresponding layer at a determined pixel, like for example the chemical and physical properties. The additional two basis maps are the depth map of the layer sole and the thickness map. The second part of modeling is represented by a set of procedures, determining the true values of the interesting parameters mentioned above for an arbitrary point or sector of the tree-dimensional space. They execute the search of that layer which is situated at the corresponding point and they support the transfer of its properties from the two-dimensional maps to that point. These procedures can be executed by means of the FORTRAN prototype program REPRES. Some examples of 3D-modeling of a Miocene lignite seam in Saxony have demonstrated the utility of the method.
