Abstract

Actual fabrics are simulated by superimposing the optical properties of 2000 individual kaolinite crystals comprising hypothetical fabric models in which the individual c-crystallographic axis directions are normally distributed about a mean direction with respect to the microscope optics. The intensities are computed for models with different mean c-axis directions and degrees of fabric randomness, which is characterized by the standard deviation of the normal distribution, and these intensities serve as a reference to which experimentally obtained intensities for thin sections of kaolinitic soils with unknown fabric are compared. An appreciation of the fabric homogeneity over the area of a thin section can be obtained by use of an equal area spherical projection plot.
