| 摘 要： | The process-facies types of the Devonian volcanic sedimentary successions in northern Xinjiang include explosive facies, effusive facies, pyroclastic-calcareous-terrigenous tempestite facies, and coarse~-, medium~- and fine-grained pyroclastic turbidite facies, volcanic eruption tsunamite facies, syndepositional and soft-deformed seismite facies, sandy and silt-muddy contourite facies. This paper presents their characteristics and diagnostic indicators, and discusses the temporal and spatial structures of both the process-facies and the environment-facies of the Zhifang section, east Junggar, and the Mount Sarburti section, west Junggar, and their relation to plate tectonism. The author holds that the facies analysis dominated by process-facies is the facies analysis' nucleus in an orogenic belt and active continental margin.
