Table 2. Bulk rock geochemistry of selected samples of volcanic rocks from Andaman ophiolites
Table 3. U-Pb data for zircon from Andaman samples

Figure captions (Supporting information)

Supplementary figure 1 Typical morphologies of zircon in the three populations investigated. Numbers correspond to those in Table 3. The grains are about 70-150 micron long.

Supplementary figure 2 N-MORB (a,d,g,j,m,p); with emphasis on LILE (b,e,h,k,n,q) and chondrite (c,f,i,l,o,r) normalized spidergram for volcanic rocks of Andaman ophiolite.

Supplementary figure 3 (a,b,c,d) primitive mantle; (e,f,g,h) chondrite normalized spidergram for clinopyroxene trace element concentration of forearc peridotites from literatures. (i,j) Domain of forearc peridotite with clinopyroxene data from Daito ridge (Morishita et al. 2018b). Clinopyroxene trace element pattern of Rutland Island peridotite is also shown.

Supplementary figure 4 (a) AFM (Irvine and Baragar, 1971) plot and trace element-based alkalinity test diagram (Ross and Bédard, 2009) (b) Th/Yb-Zr/Y; (c) Y-Zr; (d) Yb-La, (e) Yb-Th for volcanic rocks of Andaman ophiolite
