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