AB We present a study of the Mg K-edge on sepiolite and palygorskite performed at the INFM BEAR beamline at Elettrasynchrotron light source (Trieste). These two clays, although having very similar structures, show some differentfeatures in their near-edge. Mg is in octahedral coordination with oxygens, hydroxyl groups or water, for both palygorskiteand sepiolite. The differences found in the near-edge seem to reflect the fact that, on average, an Mg atomin palygorskite ‘‘sees’’ less Mg in higher coordination shells than sepiolite.
