Triassic eclogites from central Qiangtang, northern Tibet, China: Petrology, geochronology and metamorphic P-T path

► The Qiangtang metamorphic belt lies in the northern Tibetan plateau and consists of blueschist and elcogite. ► Eclogite formed in a relatively low P-T environment. ► U-Pb and Ar-Ar datings show that the eclogite formed in the Triassic. ► Eclogites were formed by northward subduction of the Paleo-Tethys Ocean.
