Oxygen and carbon isotope data from late calcite and zeolite pore-fill cements at DSDP Site 445

Oxygen isotopic composition of zeolite pore-fill cements in andesitic volcaniclastic sandstones recovered from DSDP Site 445 ranges from +30.1 to +17.8‰ (SMOW) downhole. This change is controlled by large heat flow from the basement which caused early diagenetic emplacement of zeolites during early basin rifting. d18O-values of late calcite cements range from +25.1 to +27.4‰ (SMOW); their petrographic relation and inferred temperature of formation suggest that calcite cements were formed during late stages of diagenesis. Isotopic composition in these sandstones is in agreement with mineral paragenesis determined microscopically.
