Description

Uranium contents of 67 oceanic basalts have been measured by fission track analysis. Average value for ridge and intraplate basalts is approximately 78 ppb, for the Easter Hot Line it is approximately 1600 ppb. Estimates of mantle concentrations derived from the ridge and intraplate samples are insufficient to account for the observed surface heat flow. The whole-Earth concentration of U is > 8 ppb, and < 33 ppb if all heat generated within the Earth reaches the surface. (author)
