The Zig-Zag Nature of Type I and Type IV Curves

Previous HitWilliamNext Hit F. Tanner


Many distributions of sedimentologic (and other geologic) data are non-Gaussian. Of nine examples studied in detail, seven are Previous HitPearson'sNext Hit Type IV, and two are Previous HitPearson'sTop Type I. Each plots as a zig-zag line composed of two or more straight-line segments on probability paper. The zig-zag pattern appears to be caused by a deficiency of particles of certain sizes. This is perhaps a general, rather than a local, condition, as has been pointed out by many workers.
