| contents | Calcite in the cavities and veins of igneous rocks has long been recognized as an alteration by-product (Dana, 1892). Elementary mineralogy textbooks report that the most common occurrence of aragonite is in the cavities of basalts and andesites (e.g., Kerr, 1977). Therefore, it is not surprising to find both carbonate minerals in association with the moderately to extensively altered basalt flows recovered during deep sea drilling on Suiko Seamount in the Emperor Seamount chain (DSDP Leg 55, Hole 433C). The thickness and vesicularity of the flows, along with the presence of oxidized flow tops, indicate that the basalt erupted subaerially (Site 433 Report, 1980). The stable isotopic contents of the carbonate phases filling and lining the veins and vesicles denote the environment of alteration. An isotopic study was undertaken to secure supportive evidence for a subaerial period in the development of the seamount. Also, the subsequent alteration history after submergence may be interpreted from this isotopic record. |
