Abstract
The markov matrix and information entropy have been used for analyzing successions of sedimentary rock and modeling of hydrogeological environment in wide groundwater basin. In this study, these techniques were applied to evaluate recognizable pattern of a fracture distribution using boreholes data. The changing pattern of fracture frequencies along boreholes were calculated by using the markov matrix and Information entropy. As a result of the calculations, it was found that the fracture frequencies could be well described by using these techniques, and the thickness of low fracture frequency zone was estimated.
