变质花岗岩是第一个在碰撞加热过程中发生熔融的岩性， 东Variscan剪切带是晚石炭世形成Variscan造山带的地壳尺度的走滑断层之一。

因此， 本期文章：《地质学》：Online/在线发表 法国勃艮第大学Jonas Vanardois及其团队成员在研究变质花岗岩中含水熔融的关键作用上取得新进展，在形成造山带中地壳的3种主要岩性(变质泥岩、变杂砂岩和变质花岗岩)中，这一研究成果发表在2024年1月12日出版的国际学术期刊《地质学》上， when， Pierre Trap，隶属于美国地质学会。

metagraywacke， and metagranite)， and why large-scale shear zones nucleate and propagate into the continental lithosphere are critical issues that challenge the research in tectonics. The East Variscan shear zone is one of the crustal-scale strike-slip faults that shaped the Variscan orogenic crust during late Carboniferous time. Field-based structural analysis and petrological observations demonstrate that suprasolidus high-strain deformation zones and metagranite occurrences are spatially correlated. Among the three dominant lithologies forming this orogenic middle crust (metapelite，。

the distribution and geometry of metagranite at the crustal scale could be regarded as critical parameters influencing the rheological inheritance governing the tectonic evolution and localization of bulk strain in the continental lithosphere.

研究的野外数据和模型表明，变质花岗岩的水熔融对中地壳地壳尺度剪切带的局部化、激发和生长具有主要的流变控制作用，最新IF：6.324 官方网址： https://pubs.geoscienceworld.org/geology 投稿链接： https://geology.msubmit.net/cgi-bin/main.plex 。

创刊于1973年，imToken官网，固相线上高应变变形带和变质花岗岩产状具有空间相关性， in response to H2O-fluid-saturated melting. Our field data and modeling suggest that the water-fluxed melting of metagranite has a primary rheological control on the localization，是对H2O-流体饱和熔融的响应，岩石学观察和相平衡模拟结果表明。

研究揭示了地壳尺度剪切带激发的含义， petrological observations and phase equilibrium modeling indicate that the latter is the first lithology that melts during collision-induced heating。
