碰撞造山带的形成和演化是会聚板块边缘的显著特征，一般是一个复杂的过程。本文对大别山西部造山带的锆石成因、U-Pb年龄、Lu-Hf同位素组成以及地质特征进行了综合研究，以确定其多阶段演化历史。结果表明，湖湾地区洋壳的形成受到约400~430 Ma的制约，略晚于北秦岭与北中国地块的碰撞。它形成于扬子地块北缘的边缘盆地。湖湾榴辉岩的峰期变质作用发生在约310 Ma左右，大洋榴辉岩首次折返的时间约为270 Ma。新县和红安变质带的高压-超高压变质岩与其他大别-苏鲁地体的高压-超高压变质岩具有相同的时代和性质，并经历了多期折返，可作为大别-苏鲁造山带的组成部分。因此，秦岭-大别-苏鲁造山带是一个典型的多期大陆碰撞造山带，拼合过程持续了200 Ma以上。
The foramtion and evolution of collisional orogen is a prominent feature along convergent plate margins, and is generally a complex process. This article presents an integrated study of zircon genesis, U-Pb age and Lu-Hf isotope composition as well as geological characteristics for the western Dabie orogen to constrain its multi-stage evolution history. The results suggest that the formation of oceanic crust in the Huwan area was constrained at ca. 400–430 Ma, which was slightly later than the collision of the northern Qinling with the North China Block. It formed in a marginal basin in the northern margin of the Yangtze Block. The peak metamorphism of eclogite in the Huwan area occurred at ca. 310 Ma, and the timing of the initial exhumation of oceanic eclogite was about 270 Ma. The high to ultrahigh pressure (HP-UHP) metamorphic rocks in the Xinxian and the Hong’an metamorphic zones have the same ages and natures as those of the HP-UHP metamorphic rocks in the other Dabie-Sulu terrains, and also have experienced multi-stage exhumation, and thus can be taken as a coherent part of the Dabie-Sulu orogen. Therefore, the Qinling-Dabie-Sulu orogen is a typical multi-stage continental collision orogen, with an amalgamation process extending more than 200 Ma.
