Abstract
The Ordovician siliceous-aluminous nodules of the Armoricain Massif are mad e up of terrigenous constituents (quartz/phyllosilicate) and biogenic const ituents (silica and apatite). The nodules were formed during the early diag enesis. Their formation could be linked to processes of sedimentary condens ation governed by eustatic variations in the distal shelf.
