Objective The Babu ophiolite in Malipo County of southeastern Yunnan is interpreted as remanant ocean crust and represents a possible branch of Paleo-Tethyan Ocean in South China.It consists mainly of mafic and ultramafic rocks.These rocks are very important to understand the evolution of the Paleo-Tethyan Ocean.However,the Babu ophiolite is still disputed and the mafic and ultramafic rocks have been inferred to be part of the Emeishan large igneous province(LIP)by some researchers.In this paper,we present zircon U-Pb data on the metabasalts in Malipo
