摘　　要：The Beishan orogen,located in the central segment of the Tianshan–Solonker suture within the southern Central Asian Orogenic Belt(CAOB),is crucial for understanding the accretionary processes and continental growth in Central Asia.This orogen developed through the episodic amalgamation and accretion of continental margin arcs,island arcs,ophiolites,and accretionary wedges,undergoing a complex process of accretion and evolution.Since the Phanerozoic,the Beishan orogen has experienced multiple phases of magmatic and collision events.The intricate distribution of magmatic arc rocks has obscured the complete basement traces,and the spatial superposition of multiple magmatic arc phases has complicated the study of its evolutionary history.
