La microplaque de l'île de Pâques (Pacifique Sud Oriental): variations isotopiques Pb-Sr-Nd

Publication date1991
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.
