摘要: The mantle and continental crust contain excessive amounts of radiogenic lead, implying that a complementary reservoir unradiogenic lead should exist somewhere on Earth. Isotopic analyses rocks exposed the Atlantic Ocean floor reveal sulphide inclusions can have extremely compositions, suggesting could within itself.
