Primitive Mantle 70 Yb 0.4144           ppm Trace element abundances in the Earth's Primitive mantle given in ppm as was first found by Hart and Zindler 1986. The major element factor of 2.51 was used to obtain the mantle values of the refractory trace elements from the abundances of C1 Carbonaceous chondrites. Hofmann 1988 Hart & Zindler 1986
