Numerous minette dykes intersect the Precambrian crystallinebasement of Schirmacher Oasis, East Antarctica. This study presentsnew Sr, Nd, Pb and O isotope data for 11 minette samples fromfour different dykes. The samples are characterized by relativelyhigh ⁸⁷Sr/⁸⁶Sr (0·7077–0·7134), ²⁰⁷Pb/²⁰⁴Pb(15·45–15·55) and ²⁰⁸Pb/²⁰⁴Pb (37·8–39·8),combined with low ¹⁴³Nd/¹⁴⁴Nd (  相似文献
