Fig. 4: Trace element ratios of the studied samples.

From: A HIMU-like component in Mariana Convergent Margin magma sources during initial arc rifting revealed by melt inclusions

Fig. 4

Plot of Th/Yb versus Nb/Yb (a) and Ba/Yb versus Th/Yb (b) for studied melt inclusions and their host whole-rocks. The red arrow represents mantle source enrichment and the blue arrow shows the addition of the subduction component. Subducted sediment is an important factor in changing the trace element ratios of samples. End-member data are from ref. 94 and Supplementary Data 6.
