摘要	Previous researches have recognized Heilongjiang Group as a suit of tectonic melange including blue schists and discovered subducting oceanic slabs under the lower crust of Zhangguangcai Range. This work is aimed at restoration of the orogenic processes related with the subduction by studying the strata-formation, magmatism,. and deformation-metamorphism of Zhangguangcai Range. A geological investigation across the orogenic belt from east to west reveals that the temporal and spatial distributions of the sedimentary facies and strata thickness, volcanic rock combination and granite series, and metamorphic degree and deformation strength are controlled by subduction-collision orogeny. The orogenic belt can be divided into four sub-belts among which two are horizontally accreted tectonic m lange belts and the other two vertically accreted epicontinental arc-magmatic belts. A preliminary chronological study indicates that the arc-magmatism related with the subduction occurred at the end of the Late Triassic and the beginning of the Jurassic, and that the metamorphism forming high-pressure blue schists and medium-high pressure chloritoid-garnet schists and compress-shear deformation appeared in the Early-Middle Jurassic. The latter processes were related with the continuous westward compression of Jiamusi terrane in the same period. A comparative research of areal structures reveals some common features of the Mesozoic orogeny in Zhangguangcai Range and that in the west of North America.
