Oxygen isotopic analyses of these clays, and associated calcite, indicate a formation temperature of \u0026lt;25°C.Celadonite contains appreciable Fe2O3, K2O and SiO2, intermediate MgO, and very little Al2O3. Celadonite is commonly associated with goethite and hematite, which suggests that this phase formed by precipitation within a dominantly oxygenated environment of components leached from basalt and provided by seawater. A mass balance estimate indicates that celadonite formation can remove no more than 15% of the K annually transported to the oceans by rivers. In contrast, iron-rich saponite containing significant Al2O3 appears to have precipitated from a nonoxidizing, distinctly alkaline fluid containing a high Na/K ratio relative to unmodified seawater.Seawater-basalt interaction at low temperatures, resulting in the formation of celadonite and smectite may explain chemical gradients observed in interstitial waters of sediments overlying basalts.","descriptionType":"Abstract"},{"description":"Supplement to: Seyfried, W E; Shanks, Wayne C; Dibble, W E (1978): Clay mineral formation in DSDP Leg 34 basalt.
