Axial longitudinal flow in volcanic materials of the late carboniferous-permian Cadí basin (Southern Pyrenees) determined from anisotropy of magnetic susceptibility

The aim of this work is the application of the anisotropy of magnetic susceptibility (AMS) to the study of volcanic materials from the Late Carboniferous-Permian Cadí basin (southern Pyrenees) in order to (i) explore the limits of this technique in ancient volcanic materials that have undergone stro...
