p.17: Detritic unit: the contact with the Graphitic unit is always clear-cut. Strikingly, the Detritic unit is in contact only with the calcareous micaschist and never with the black micaschist. The detrital input shows a clear evolution: the deposit begins with a hard, grey argillaceous-rich quartzitic metasandstone that becomes riches in dolomitic detritic grains towards the top. It simulates a paragneiss and contains locally centimetric pyrite crystals. This deposit suddenly ends with the abrupt shedding of a very quartz- and clay-poor dolomitic metasandstone. The whole unit has a maximum thickness of 20-25 m.
