Abstract

A study of the Sm-Nd isotope composition of Honguleleng ophiolite in Xinjiang, China, isochron age ((626±25)Ma),εNd(t) =8.40,and its model age (T NdDM ) in the range of 1 180–1 208 Ma, indicates that the ophiolite was formed in the late stage of the Upper Sinian. In combination with its facies association, petrochemistry, REE patterns, trace elements and associated chromites orebodies, it is believed that the Honguleleng ophiolitic magma derived from the LREE-enriched, self-depleted mantle source and formed at paleo-ocean ridge. This ophiolite is a relic of an oceanic crust within the collision zone.
