One of the main interests in the determination of the low field anisotropy of magnetic susceptibility (AMS) is its value as a petrofabric indicator. An important part of the interpretation of AMS measurements in this context involves the orientation of the principal susceptibilities. Several methods of calculating mean directions of the principal susceptibilities, and associated regions of confidence have been devised, but the tensor‐averaging technique will provide a better estimate in most circumstances (Ernst and Pearce, 1989). Also, different methods have been proposed to estimate regions of confidence around the mean principal susceptibilities. When the individual measurements are not very different from the calculated mean (in which case it is said that the uncertainty is not large), the regions of confidence calculated with different methods are similar to each other and exert a small influence in the interpretation of results. When the uncertainty in the mean susceptibility is...
