AB: In this paper we present a study of intrinsic anisotropy focusing on stratification of poured sediments using Vp. We describe the experimental procedure to detect the intrinsic anisotropy with Vp in sand and glass bead samples. We then offer a method to determine textural anisotropy with the spatial autocorrelation function. In this method we use the spatial autocorrelation function and its variation with direction to characterize the stratification texture from images of the samples. To determine if there is a relation between Vp and the textural anisotropy, we compare velocity anisotropy and the spatial autocorrelation function. We find that velocity anisotropy reveals internal packing.
