Abstract

Dredged basalt samples from the Easter Island microplate show a very large local variety of isotope data with e.g. Nd values between 0.51328 and 0.51285. In the eastern branch they differ considerably from normal East Pacific Ridge values. ²⁰⁶Pb/²⁰⁴Pb, ⁸⁷Sr/⁸⁶Sr and ¹⁴³Nd/¹⁴⁴Nd ratios from the Easter island microplate (EMP) are intermediate between Sala y Gomez and MORB.
