The Iranian plateau has a more straightforward relationship between the Paleo-Tethys and Neo-Tethys, than other regions in the Tethyan realm and is an ideal place to test the genetic connection of how the Paleo-Tethys affected the Neo-Tethys. Moreover, there is no consensus on how Paleo-Tethyan evolution influenced the Neo-Tethyan Wilson cycle. We studied the petrology, geochemistry, and metamorphic age of an eclogite suite at Rasht in northern Iran from the Paleo-Tethyan suture. The eclogitic protolith was a typical mid-ocean-ridge basalt and achieved its peak metamorphic condition of 2.7 GPa and 590 °C at 353 ± 8.9 Ma. Reconstructed pressure-temperature-time path of the eclogite-facies rocks suggests that the eclogitic protolith entered the trench at 356 ± 8.9 Ma. Mid-oceanic ridge rocks formed at ~380 Ma at the Rasht region and other places along the Alborz Mountain strike. A ~ 25 million years (Myr) period from the birth of oceanic crust to subduction at Rasht region implies that the mid-ocean-ridge was close to the trench. We propose that the Paleo-Tethyan mid-ocean-ridge was trench-parallelly subducted beneath the Eurasian boundary in northern Iran. This ridge-subduction propagated from east to west between 380 and 355 Ma. 47–27 Myr after ridge consumption, subduction of the remaining Paleo-Tethyan oceanic crust exerted a continuous extensional stress of ~0.1 GPa on the passive margin of Gondwana since the late Carboniferous. The drag-force eventually detached the Central Iranian Block from Gondwana, and opened the Neo-Tethyan ocean during the middle-late Permian.

与特提斯王国的其他地区相比，伊朗高原与古特提斯人和新特提斯人之间的关系更为直接，是测试古特提斯人如何影响新特提斯人的遗传联系的理想场所。此外，关于古特提斯演化如何影响新特提斯威尔逊循环还没有达成共识。我们从古特提斯缝合线研究了伊朗北部拉什特榴辉岩套件的岩石学、地球化学和变质年龄。榴辉岩原岩是典型的洋中脊玄武岩，在 353±8.9 Ma 时达到了 2.7 GPa 和 590 °C 的峰值变质条件。榴辉岩相岩石的重建压力-温度-时间路径表明榴辉岩原岩在356±8.9 Ma进入海沟。洋中脊岩石形成于约 380 Ma，位于拉什特地区和阿尔伯兹山走向的其他地方。从大洋地壳的诞生到拉什特地区的俯冲大约有 2500 万年 (Myr) 的时间，这意味着大洋中脊靠近海沟。我们认为古特提斯洋中脊在伊朗北部的欧亚边界下平行海沟俯冲。这种脊俯冲在 380 至 355 Ma 之间从东向西传播。47-27 Myr 在山脊消退后，自晚石炭纪以来，剩余的古特提斯洋壳的俯冲对冈瓦纳被动边缘施加了~0.1 GPa 的连续拉伸应力。阻力最终使伊朗中部地块与冈瓦纳大陆分离，并在二叠纪中晚期打开了新特提斯洋。从大洋地壳的诞生到拉什特地区的俯冲大约有 2500 万年 (Myr) 的时间，这意味着大洋中脊靠近海沟。我们认为古特提斯洋中脊在伊朗北部的欧亚边界下平行海沟俯冲。这种脊俯冲在 380 至 355 Ma 之间从东向西传播。47-27 Myr 山脊消耗后，自晚石炭纪以来，剩余的古特提斯洋壳的俯冲作用对冈瓦纳大陆被动边缘施加了~0.1 GPa 的持续拉伸应力。阻力最终使伊朗中部地块与冈瓦纳大陆分离，并在二叠纪中晚期打开了新特提斯洋。从大洋地壳的诞生到拉什特地区的俯冲大约有 2500 万年 (Myr) 的时间，这意味着大洋中脊靠近海沟。我们认为古特提斯洋中脊在伊朗北部的欧亚边界之下平行海沟俯冲。这种脊俯冲在 380 至 355 Ma 之间从东向西传播。47-27 Myr 山脊消耗后，自晚石炭纪以来，剩余的古特提斯洋壳的俯冲作用对冈瓦纳大陆被动边缘施加了~0.1 GPa 的持续拉伸应力。阻力最终使伊朗中部地块与冈瓦纳大陆分离，并在二叠纪中晚期打开了新特提斯洋。我们认为古特提斯洋中脊在伊朗北部的欧亚边界下平行海沟俯冲。这种脊俯冲在 380 至 355 Ma 之间从东向西传播。47-27 Myr 山脊消耗后，自晚石炭纪以来，剩余的古特提斯洋壳的俯冲作用对冈瓦纳大陆被动边缘施加了~0.1 GPa 的持续拉伸应力。阻力最终使伊朗中部地块与冈瓦纳大陆分离，并在二叠纪中晚期打开了新特提斯洋。我们认为古特提斯洋中脊在伊朗北部的欧亚边界下平行海沟俯冲。这种脊俯冲在 380 至 355 Ma 之间从东向西传播。47-27 Myr 山脊消耗后，自晚石炭纪以来，剩余的古特提斯洋壳的俯冲作用对冈瓦纳大陆被动边缘施加了~0.1 GPa 的持续拉伸应力。阻力最终使伊朗中部地块与冈瓦纳大陆分离，并在二叠纪中晚期打开了新特提斯洋。自晚石炭世以来，剩余的古特提斯洋地壳的俯冲作用对冈瓦纳被动边缘施加了~0.1 GPa的连续拉伸应力。阻力最终使伊朗中部地块与冈瓦纳大陆分离，并在二叠纪中晚期打开了新特提斯洋。自晚石炭世以来，剩余的古特提斯洋地壳的俯冲作用对冈瓦纳被动边缘施加了~0.1 GPa的连续拉伸应力。阻力最终使伊朗中部地块与冈瓦纳大陆分离，并在二叠纪中晚期打开了新特提斯洋。
