Abstract
THE USE OF SURFACE TREND IN EVALUATION OF RELIEF AND SURFACE OF DEPOSITS
Summary
The surface trend was introduced as a method of generalization of spatial pattern of a studied phenomenon in geophysics and geology in the end of the fifties. It was widely used thereafter, appearing useful for reconstructing physically recorded surfaces, difficult to trace because of disadvantageous location, and constructing surfaces impossible to record by physical methods. Three-dimensional trends of the type Z = f(x, y) are commonly used in geological and geographic studies. However, four-dimensional-trends of the form Z = f(x, y, w) appear of much higher potential. In geology the latter trends may be used for:
1) numerical reconstruction of geological layers,
2) graphic presentation of the reconstructed pattern of layers, and
3) calculations of volume of a layer.
Questions connected with solving of the above tasks are discussed in detail. In order to illustrate practical aspects of the use of the four-dimensional trend in geology, it was applied to reconstruct brown-coal sedimentary series in a part of the Jóźwin deposit.
