Chondrodonta sp. and requienid shells show a better degree of chemical preservation, whereas caprotinid and monopleurid shells seem to be more affected by diagenetic fluids. The same conclusion can be obtained when 87Sr/86Sr values are plotted against cationic contents in Sr, Na, Mg, Fe and MnspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Strontium isotopesRudistMiddle CretaceousDiagenetic degreejournal articleopen access
