The sandstones in the lower part of the rift record have not suffered this Received in revised form 13 April 2012 albitization process. A clear relationship is observed between sodium contents, as the main element of some feld- Accepted 16 April 2012 spars and their cathodoluminescence (CL) color (the higher the sodium content, the lower is their CL intensity).
