Coaxial deformed and magnetic fabrics without simply correlated magnitudes of principal values

Results of a detailed strain analysis of accretionary lapilli in the Borrowdale Volcanic sequence of England indicate a bedding-memory component to the rock's fabric. A simple, new strain analysis method uses variation in thickness of lapilli rims and appears not to be influenced by the bedding fabric. The orientations of the principal magnetic susceptibilities show a strong correlation with the principal strain orientations, as in other studies, but we can detect no correlation between strain magnitudes and principal susceptibility magnitudes in the same small specimens.
