•Toudaoqiao blueschists were metamorphosed up to HP epidote–blueschist facies.•Blueschists have OIB and N-MORB affinities.•Timing of HP metamorphism at 490–510Ma.•Toudaoqiao–Xinlin fault is the suture between the Erguna and Xing’an blocks. The Toudaoqiao Complex is a sequence of high-pressure metamo...
