Figure 7: Concordia diagrams and REE plots.
From: Partial melting of deeply subducted eclogite from the Sulu orogen in China
(a) Concordia diagram and weighted average age of one leucosome sample with representative zircon CL images. (b) Concordia diagram and weighted average age of one residue sample with representative zircon CL image. (c) Concordia diagram and weighted average age of one mixture sample contains both leucocratic and residual material (melting process stage II) with representative zircon CL image. (d) Chondrite-normalized REE patterns of two representative leucosome samples, two residue samples, one UHP stage-1 eclogite and one UHP stage-2 stage eclogite. Compositionally, the REE of the leucosome are comparable with the standard upper continental crust (UCC) by Rudnick & Gao48. See Supplementary Data Set 4 and 5 for original data and analyses. The weighted average age calculation is based on the 206Pb/238U since the formation age is younger than 1,000 Myr ago. Age data processing was carried out with ISOPLOT software, the error ellipses are the absolute error value and 1σ. Scale bars in the zircon CL images are 50 μm across.
