中文摘要:

collisional orogen 的 foramtion 和进化是沿着会聚的板边缘的一个突出的特征,并且通常是一个复杂过程。这篇文章象地质的特征一样介绍锆石开始, U-Pb 年龄和 Lu-Hf 同位素作文的综合研究让西方的 Dabie orogen 抑制它的多级式的进化历史。结果建议在 Huwan 区域的海洋的外壳的形成在 ca 被抑制。400 430 妈,它比有北方中国块的北 Qinling 的碰撞稍微迟了。它在扬采·布洛克的北边缘在边缘的盆形成了。在 Huwan 区域的 eclogite 的山峰变态发生在 ca。310 妈,并且预定海洋的 eclogite 的起始的发掘是大约 270 妈。高度到超离频压力( HP-UHP )在 Xinxian 和 Hong'an 的变形岩石变形地区在另外的 Dabie-Sulu 地面有 HP-UHP 变形岩石的象那些的一样的年龄和性质,并且也经历了多级式的发掘,并且能因此作为 Dabie-Sulu orogen 的协调部分被拿。因此, Qinling-Dabie-Sulu orogen 是典型多级式的大陆人碰撞 orogen,与扩大超过 200 妈的一个合并过程。

英文摘要:

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.
