Water and carbon in the Earth's mantle
The concentrations of H2O and C in mid-ocean ridge basalts indicate that the upper, degassed, part of the mantle contains approximately 200 ppm H2O and 80 ppm C. Estimates for the bulk silicate earth are less precise, but, from geochemical and cosmochemical arguments, values of 550-1900 ppm for H2O...
