Resumen
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
