AB Detailed petrographic observations of Upper Proterozoic –Lower Cambrian deposits of the Castañar de Iborallows the characterization of the diagenetic history of these rocks. Graywackes, shales and limestones weredeposited during the Upper Proterozoic-Lower Cambrian within a siliciclastic-carbonatic marine platform.Dolomite replaced mostly limestones, but also cemented the siliciclastic deposits. Later on magnesium-richfluids circulating along stylolites, bedding planes and fractures partially replaced the dolostones and somesiliciclastic beds. Finally, a new dolomitisation phase produced replacement of the magnesite by dolomite anddolomite cementation.
