Fisher distribution fracture sets
WebJun 14, 2024 · A number of clusters were fixed with a visual inspection of the data, aided by density contouring of fracture poles. The output includes the orientation of the fracture sets, the Fisher’s dispersion factor (i.e., K value, Fisher, 1953), and the mean cone angle (MCA) enclosing the data distribution. WebIn theory, the joint orientations of each fracture set can be determined by a Fisher distribution, Bingham distribution, bivariate normal distribution, or bivariate empirical distribution [40,42,43,44,45]. However, due to the complexity of the geological structure and investigation error, it is very difficult to determine a distribution that ...
