Abstract

Coesite and omphacite inclusions have been identified for the first time as minute inclusions in zircon from amphibolite-facies granitic orthogneiss in the Sulu ultrahigh-pressure (UHP) metamorphic terrane of eastern China by Raman spectroscopy and microprobe analyses. The occurrences of these minerals in the voluminous granitic gneiss of Sulu support a regional and pervasive UHP metamorphic event that predated regional amphibolitic retrogression. Taking into account the widespread discoveries of coesite on other lithogies, we thus conclude that a substantial crustal component in the Sulu UHP metamorphic terrane appears to have appears to have shared a common history of Triassic subduction to mantle depths and later exhumation.
