RT Journal Article T1 Inocerámidos y sedimento carbonatado (Maastrichtiense inferior, Arco Vasco): Comportamiento de la relación 180/160 y 13C/12C durante la diagénesis. (Parte II) T1 Inoceramids and carbonate sediment (lower Maastrichtian, Basque Arc): Behaviour of the 180/,(0 and 73C/12C ratios during diagenesis. (Part II) A1 Gómez Alday, Juan José A1 Elorza, Javier AB Oxygen and carbon isotopic analysis have been carried out on whole rock and inoceramid shell samples from deep-sea carbonate sediments at Sopelana II, Sopelana I and Zumaya sections (Basque Arc). The analytical results suggest that microcrystalline carbonate matrix and prismatic microstructure inoceramid shells have undergone different diagenetic paths. It is due to different isotopic mass balances which took place during fluid-carbon ate phase interaction. Under similar burial conditions, the solid phase microstructure played an important role during distribution of stable isotopes among different reservoirs PB Sociedad Geológica de España YR 2001 FD 2001 LK http://hdl.handle.net/10272/9579 UL http://hdl.handle.net/10272/9579 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 14 jul 2026
