The tectono magmatic formation of the Japan Sea: Constraints from in situ trace elements and Sr isotope of plagioclase and clinopyroxene

<strong>Table S1</strong> Major-element (wt.%) and Trace-element (ppm) concentrations of Sites 794 and 797 clinopyroxene phenocrysts from the Japan Sea. <strong>Table S2</strong> Major-element (wt.%) and Trace-element (ppm) concentrations of Sites 794 and 797 plagioclase phenocrysts from the Japan Sea. <strong>Table S3</strong> The trace element values of standard samples during the mineral analyzing process <strong>Table S4</strong> <em>In-situ</em> Sr isotopic ratios of Sites 794 and 797 plagioclase phenocrysts and groundmass from the Japan Sea. <strong>Figure</strong> <strong>S1.</strong> Chondrites-normalized REE diagrams for 127-794C-1R plagioclase (A); Primitive mantle-normalized trace element abundances diagrams for 127-794C-1R plagioclase (B). Normalizing values are cited from Sun and McDonough (1989). The plagioclase data from the crustal Low-K tholeiitic basalts (dark grey lines) and the mantle-derived Medium-K Calc-Alkaline andesites (french grey lines) in NE Japan Arc are identical with those of Fig. 6. <strong>Figure</strong> <strong>S2.</strong> The plots of 87Sr/86Sr vs. An (mol.%) (A), 87Sr/86Sr vs. Cr (ppm) (B), 87Sr/86Sr vs. MgO (wt.%) (C), 87Sr/86Sr vs. K2O (wt.%) (D) in plagioclases from Sites 794 and 797 volcanic rocks. <strong>Figure S3.</strong> The ratios of Th/Y (A), Sm/Th (B), Ta/Yb (C), La/Yb (D), Nb/Ta (E), 143Nd/144Nd (F) for Upper Site 797, Lower Site 797, Upper Site 794, Lower Site 794 tholeiitic basalts from the Japan Sea. The arrows show the trend from young to old volcanic activities in the Japan Sea. <strong>Figure</strong> <strong>S4.</strong> The plots of δEuN vs. YbN (ppm) (A), δEuN vs. ∑LREEN (ppm) (B) in plagioclases from Sites 794 and 797 volcanic rocks. The subscript ‘N' indicates chondrite-normalized values. <strong>Figure</strong> <strong>S5.</strong> Chondrite-normalized REE abundances of calculated melts in equilibrium with 127-797C-16R clinopyroxene (A) as cited from Fig. 4A; calculated melts in equilibrium with 127-794C-10R clinopyroxene (B) as cited from Fig. 4B; calculated melts in equilibrium with 128-794D-14R clinopyroxene (C) as cited from Fig. 4E; calculated melts in equilibrium with 128-794D-20R clinopyroxene (D) as cited from Fig. 4F; Clinopyroxene-liquid partition distribution coefficients are from Lee et al. (2007). The N-MORB, E-MORB, OIB, and chondrite normalizing values are from Sun and McDonough (1989).
