摘要
<正>Ocean island basalts(OIBs)recorded the chemical heterogeneity of the deep mantle,which is generally attributed to recycled crust in the source(Zindler and Hart,1986;Hofmann,1997,2003;White,2010;White,2015).Although Mg is a major element of the mantle,it is still unclear whether and how Mg isotopes of OIBs respond to such chemical heterogeneity in the deep mantle source.
