Inferences about magma sources and mantle structure from variations of 143Nd/144Nd
Open accessAbstract
Continental flood basalts and mid‐ocean ridge (MOR) tholeiitic basalts have distinctly different 143 Nd/144 Nd which may permit a priori distinction between "continental" and "oceanic" igneous rocks. Initial 143 Nd/144 Nd of continental igneous rocks through time fall on a Sm/Nd evolution curve with chondritic REE abundance ratio. These observations indicate that many continental igneous rocks are derived from a reservoir with chondritic REE pattern which may represent primary material remaining since the formation of the earth. Oceanic igneous rocks are derived from a different ancient reservoir which has Sm/Nd higher than chondritic. Initial 143 Nd/144 Nd and 87 Sr/86 Sr in young basalts from both oceans and continents show a strong correlation suggesting that Sm‐Nd and Rb‐Sr fractionation events in the mantle may be correlative and caused by the same process. From this correlation Rb/Sr for the earth is inferred to be 0.029.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
