Abstract The Cretaceous basement of the broader NW Pannonian Basin, including the Vienna Basin, has an Alpine nappe structure that can be correlated between the Eastern Alps and the Western Carpathians. For the first time in this region, based on the systematic integration of petroleum industry vintage 2D reflection seismic data with well data from Austria, Hungary and Slovakia, we document various modes of interaction between pre-existing thrust and superimposed normal faults. Whereas in some cases the pre-existing Cretaceous nappe contacts became extensional low-angle normal faults, the typical scenario is that the Miocene normal faults obliquely cut across them. The style of this negative inversion, i.e. contraction followed by extension exploiting the same fault system, is based on the orientation and geometry of the Alpine nappes in relation to the successor extensional basins. We expand our earlier findings made in the Hungarian sector of the NW Pannonian Basin where Neoalpine (Neogene) low-angle normal faults did indeed interact with abandoned Eoalpine (Cretaceous) and Mesoalpine (Paleogene) thrust fault planes, but in a more selective manner than expected before. The subsurface examples of this paper are located in the Austrian part of the Vienna Basin, the Hungarian, Austrian and Slovakian segments of the broader Danube Basin. Our new regional and local scale subsurface observations also helped to define a very large, but so far unrecognized Eocene antiformal nappe stack beneath the Danube Basin. Presently this is a highly dismembered and dominantly subsurface structure concealed beneath the NW Pannonian Basin between the Eastern Alps and the Western Carpathians. This finding has important implications for the understanding of the Alpine evolution of the broader region.

潘诺尼亚盆地下方阿尔卑斯山与喀尔巴阡山脉之间的联系：中新世延伸期间高山推覆接触的选择性重新激活

摘要 包括维也纳盆地在内的更广阔的 NW Pannonian 盆地的白垩纪基底具有高山推覆结构，可以在东阿尔卑斯山和西喀尔巴阡山脉之间进行关联。在该地区，我们首次将石油工业老式二维反射地震数据与奥地利、匈牙利和斯洛伐克的井数据进行系统整合，记录了预先存在的逆冲断层与叠加正断层之间的各种相互作用模式。虽然在某些情况下，先前存在的白垩纪推覆接触面变成了伸展的低角度正断层，但典型的情况是中新世正断层斜切穿过它们。这种负反转的风格，即利用同一断层系统先收缩后扩展，是基于与后续伸展盆地相关的阿尔卑斯推覆体的方向和几何形状。我们扩展了我们在 NW Pannonian 盆地匈牙利部分的早期发现，在那里新高山（新近纪）低角度正断层确实与废弃的上高山（白垩纪）和中高山（古近纪）逆冲断层相互作用，但比起选择性之前预计。本文的地下例子位于维也纳盆地的奥地利部分，更广泛的多瑙河盆地的匈牙利、奥地利和斯洛伐克部分。我们新的区域和局部尺度地下观测也有助于确定多瑙河盆地下方的一个非常大但迄今为止未被认识的始新世反形式推覆岩堆。目前，这是一个高度肢解且占主导地位的地下结构，隐藏在东阿尔卑斯山和西喀尔巴阡山脉之间的西北潘诺尼亚盆地下方。这一发现对于理解更广泛地区的阿尔卑斯山演化具有重要意义。
