The large portion of Central and NW Europe was subjected to widespread continental rifting since the Carboniferous-Permian transition. This process led to nucleation of several large depocentres, coalescing from the late Permian onwards into the extensive Central European Basin System (CEBS), that grew and evolved until the regional-scale Late Cretaceous inversion. Development of deep grabens from Germany to the Netherlands and the North Sea was connected with volcanism and crustal thinning. The exception makes the Mid-Polish Trough (MPT), trending NW-SE across Poland along the Teisseyre-Tornquist Zone (TTZ) at the margin of the East European Craton (EEC). The MPT is underlain by relatively thick lithosphere and its formation was not associated with volcanic activity in the direct neighbourhood. To investigate this anomaly, we compiled grids for key horizons defining the crustal architecture, separately for NW European and Polish sectors of the CEBS. Seismic reflection and well data were used to build the base Permian grid, whereas deep seismic refraction and reflection data along with constrained gravity inversion were employed to construct the top basement and Moho grids. Based on a dense net of seismic refraction profiles, the additional top Ediacaran grid was created solely for the Polish part of the CEBS. Our data show distinct crystalline crust thinning SW of the TTZ (β factor = 3.68) expressed in both shallowing of Moho and deepening of the crystalline basement. We interpret this feature as a fossilised crustal neck inherited after an Ediacaran rifting preceding the break-up of Rodinia. The early Permian rifting moderately contributed to the crustal thinning (β factor = 1.4), overprinting the primary rifted margin geometry. The 8 km deep MPT developed in front of a pre-existing crustal neck that obstructed further propagation of extensional deformation. Lithospheric mantle beneath a rift axis was probably too strong to accommodate extension but the thinner lithosphere farther west was weak enough to be stretched. Therefore, the location of the pre-existing weakness zone relative to a change in lithosphere thickness may localise a rift graben and shift the magmatism away from the surface expression of the rift. Thus, our study demonstrates that fossil crustal architecture was a key factor controlling the amount, distribution, and style of continental rifting.

自石炭纪-二叠纪过渡以来，欧洲中部和西北部大部分地区经历了广泛的大陆裂谷。这一过程导致了几个大型沉积中心的成核，从二叠纪晚期开始合并到广泛的中欧盆地系统（CEBS），该系统不断发展直至区域性晚白垩世反转。从德国到荷兰和北海的深grab地带的发展与火山作用和地壳变薄有关。例外是中波兰槽（MPT），沿波兰北部NTE-SE沿Teisseyre-Tornquist区（TTZ）在东欧Craton（EEC）的边缘趋势。MPT的岩石圈相对较厚，其形成与直接邻区的火山活动无关。为了调查这个异常，我们针对CEBS的欧洲西北部和波兰部分，分别为定义地壳结构的关键层级编辑了网格。地震反射和井数据被用来建立基础的二叠纪网格，而深地震折射和反射数据以及受约束的重力反演被用来构造顶部基底和莫霍面网格。基于密集的地震折射剖面网，仅为CEBS的波兰部分创建了额外的顶部Ediacaran网格。我们的数据显示，在Moho变浅和结晶基底加深中，TTZ的结晶结壳变薄SW（β因子= 3.68）。我们将此特征解释为在罗迪尼亚（Rodinia）解体之前，埃迪卡拉（Ediacaran）裂谷后遗留下来的化石壳颈。早期的二叠纪裂谷对地壳变薄有一定贡献（β因子= 1.4），覆盖了主要裂谷边缘的几何形状。8公里深的MPT在预先存在的地壳颈前发展，阻碍了伸展形变的进一步传播。裂谷轴下方的岩石圈地幔可能太强而无法扩展，但更西端的较薄岩石圈却弱到无法伸展。因此，相对于岩石圈厚度变化而言，先前存在的薄弱区域的位置可能使裂谷被局部定位，并使岩浆作用远离裂谷的表面表现。因此，我们的研究表明化石地壳结构是控制大陆裂谷数量，分布和样式的关键因素。8公里深的MPT在预先存在的地壳颈前发展，阻碍了伸展形变的进一步传播。裂谷轴下方的岩石圈地幔可能太强而无法扩展，但更西端的较薄岩石圈却弱到无法伸展。因此，相对于岩石圈厚度变化而言，先前存在的薄弱区域的位置可能使裂谷被局部定位，并使岩浆作用远离裂谷的表面表现。因此，我们的研究表明化石地壳结构是控制大陆裂谷数量，分布和样式的关键因素。8公里深的MPT在预先存在的地壳颈前发展，阻碍了伸展形变的进一步传播。裂谷轴下方的岩石圈地幔可能太强而无法扩展，但更西端的较薄岩石圈却弱到无法伸展。因此，相对于岩石圈厚度变化而言，先前存在的薄弱区域的位置可能使裂谷被局部定位，并使岩浆作用远离裂谷的表面表现。因此，我们的研究表明化石地壳结构是控制大陆裂谷数量，分布和样式的关键因素。裂谷轴下方的岩石圈地幔可能太强而无法扩展，但更西端的较薄岩石圈却弱到无法伸展。因此，相对于岩石圈厚度变化而言，先前存在的薄弱区域的位置可能使裂谷被局部定位，并使岩浆作用远离裂谷的表面表现。因此，我们的研究表明化石地壳结构是控制大陆裂谷数量，分布和样式的关键因素。裂谷轴下方的岩石圈地幔可能太强而无法扩展，但更西端的较薄岩石圈却弱到无法伸展。因此，相对于岩石圈厚度变化而言，先前存在的薄弱区域的位置可能使裂谷被局部定位，并使岩浆作用远离裂谷的表面表现。因此，我们的研究表明化石地壳结构是控制大陆裂谷数量，分布和样式的关键因素。
