a1, a2 Chondrite-normalized REE patterns and primitive—mantle normalized diagrams for the Ulgey ophiolite. b1, b2 chondrite—normalized REE patterns and primitive-mantle normalized diagrams for the Gurvan Sayhan ophiolite. c1, c2 Chondrite—normalized REE patterns and primitive-mantle normalized diagrams for the Zoolen ophiolite. d Representative CL images of zircons from the ophiolites. e Zircon U–Pb concordia diagram for the gabbro of the Ulgey ophiolite. f Zircon U–Pb concordia diagram for the plagiogranite of the Gurvan Sayhan ophiolite. g Zircon U–Pb concordia diagram for the high-Mg diorite of the Zoolen ophiolite. h Radiometric age histograms for the Cambrian ophiolites and high-grade metamorphic rocks in the CAOB. Geochemical normalizing values are from Sun and McDonough43. Data sources of IBM forearc basalts are from Reagan et al.44.
