RT Journal Article T1 Resistencia a la alteración diagenética de conchas de Chondrodonta sp en las calizas rojas del Aptiense – Albiense inferior de Ereño (Bizkaia) T1 Resistance to diagenetic alteration in Chondrodonta sp shells from the Aptian – Lower Albian red limestones ofEreño (Bizkaia) A1 Damas Mollá, Laura A1 Aranburu Artano, Arantza A1 García Garmilla, Francisco AB Chondrodonta sp. shells from Aptian – Lower Albian red limestones of Ereño (Bizkaia, northern Spain)have proved to be excellent indicators of a high resistance to the entrance of diagenetic fluids and furtherdiagenetic alteration. Chondrodonta sp. shells, when compared to their coeval rudist shells, show higherSr+2 and Na+ contents, together with very dull or even null luminescence. For this reason they could bevery appropriate for further C, O an Sr isotopic studies as a tool for reconstruction of palaeotemperaturesand palaeoenvironmental conditions PB Sociedad Geológica de España YR 2006 FD 2006 LK http://hdl.handle.net/10272/8628 UL http://hdl.handle.net/10272/8628 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
