Lithium and rubidium concentrations in waters of seas and oceans, supplement to: Morozov, Nikolay P (1968): Geochemistry of rare alkaline elements in the oceans and seas. Oceanology, 8, 169-178
Data on lithium, rubidium and cesium concentrations in waters of open seas and oceans are summarized. Average amounts of these elements in the World Ocean inferred from published data and those obtained by the author are as follows: Li - 0.18 mg/l, Rb - 0.12 mg/l and Cs - 0.004 mg/l. Rare alkaline e...

| Summary: | Data on lithium, rubidium and cesium concentrations in waters of open seas and oceans are summarized. Average amounts of these elements in the World Ocean inferred from published data and those obtained by the author are as follows: Li - 0.18 mg/l, Rb - 0.12 mg/l and Cs - 0.004 mg/l. Rare alkaline elements in the oceans and open seas are distributed (like sodium and potassium) in accordance with salinity. The ability of lithium to become a constituent of clay minerals accounts for its relatively low concentration in sea water as compared with that of sodium and potassium. Compared to rubidium and cesium that have high absorption energy and low hydration energy, lithium relatively enriches sea water. Residence times of these elements in the ocean are: Na - 120 My, Li - 2.7 My, Rb - 2.3 My and Cs - 0.3 My. |
