In this work the question about the rock-fabric acquisition in mud rocks is analyzed in unconsolidated sediments affected by mud cracks. In this work we study the magnetic fabric (AMS) of three types of fossil and recent mud cracks in order to determine the applicability of this technique to identify the early process involved in the rock-fabric acquisition. The obtained results indicate that the magnetic fabric agrees with a isotropyc process similar to a radial contraction. It is emphasized the interest of the AMS technique to investigate the earliest stages of the rock-fabric acquisition.
