Craywackes, shales and limestones were deposited 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-rich fluids circulating along stylolites, bedding planes and fractures partially produced the replacement of the dolostones and some siliciclastic beds. Finally a new dolomitisation phase produced replacement ofthe magnesite by dolomite and dolomite cementationspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/MagnesitaDolomitaDiagénesisReemplazamientosTalcojournal articleopen access
