Figure 5: Geochemical plots of ten rock pairs of leucosome and residue.
From: Partial melting of deeply subducted eclogite from the Sulu orogen in China
These samples were collected in the region between two quartz porphyry dikes of Fig.1c. (a) Geochemical plot of Yangkou Bay leucosome and residue samples in the Nb/Y versus Zr/TiO2 ratio diagram from58. (b) Distribution of Yangkou Bay leucosome samples in the FeOtotal-Na2O+K2O-MgO ternary diagram from ref. 59, wt.%, weight percent. (c) Diagram for Sr/Y ratios versus Y contents (p.p.m.) for the Yangkou Bay leucosomes. The fields for adakites and typical arc rocks are after Defant and Drummond51. See original data from Supplementary Data Set 1 and 2.
