%X The protoliths for different types of UHP metamorphic rocks- eclogite, garnet amphibolite, paragneiss and orthogneiss in the south Sulu UHP metamorphic terrane formed under the extensional environment at the passive continental margin composed of continental basaltic rocks, supercruct rocks and granites. Zircon SHRIMP U-Pb dating for the south Sulu UHP metamorphic rocks in the CCSD-MH shows 780 - 680Ma ages for the protoliths of granitic gneiss, 765 - 730Ma ages for protoliths of eclogite and garnet amphibolite; as well as 730Ma, 680Ma, 621Ma, and even yonger ages for inherited detrital zircons and magmatic zircons of paragneiss. Aboved-mentioned dating combined with previous data shows that the protoliths of the south Sulu UHP metamorphic rocks had been inferenced by Neoprotorozoic Rodinia supercontinent breakup event represented by granitic and basic magmatisms. The supercruct protolith of paragneiss as volcano-sedimental covers of the Yangtze passive continental margin formed during Neoprotorozoic-Paleozoic. Both of them had experienced UHP metamorphism during 240 - 220Ma.
