Rosiwal intercept method

Figure 2.16. Random tracks drawn across a dispersed set of fineparticle profiles can be used to characterize the important features of the array. This type of evaluation is known as the Rosiwal intercept method, a) Array of Figure 2.15(a) converted to circles of equal area, b) Random lines can be used to generate a set of intercept tracks, c) Random lines used to inspect a random distribution are no better than using a set of parallel lines, (i) Parallel lines on the dispersion. (ii) Data generated by the set of parallel lines.

Many of the appropriate statistical relationships involved in the assessment of rock structure by techniques such as the Rosiwal intercept method are to be found in F. Chayes, Petrographic Model Analysis, Wiley, Newlfork, 1956.
