第四纪景观演化的GödöllIgnHills是由结构和气候相关的侵蚀过程。大量的新构造变形已经被记录下来，表现为深部早期正断层的反转和同裂谷后张性走滑带（Tápió-Tóalmás带（TaTZ）和相关雁列褶皱）的逆冲再活化。构造反转主要表现为前第四纪最上层的褶皱和地表变形，反映了上新世晚期-第四纪（104 -0 Ma）的压扭挤压变形，最大水平应力轴为NE-SW向。排水异常常常与新构造构造有关。背斜枢纽的抬升导致了地表侵蚀、河流盗采和放射状水系的发展。在中新世上部地层中，地表起伏幅度相对于褶皱幅度较小，反映了新构造阶段（上新世晚期至第四纪早期）早期地表的同褶皱剥蚀。另一方面，北西-南东向的直线地貌特征不受构造控制，它们主要是由通缩形成的。初步数字高程模型分析、实地研究和地下结构要素测绘相结合，证明能够成功地区分在新构造控制下或没有新构造控制的情况下形成的地貌。受新构造构造控制的地貌的存在表明中央潘诺尼亚盆地正在发生变形。
Quaternary landscape evolution of the Gödöllő Hills was governed by both structural and climate-related erosional processes. Considerable neotectonic deformation has been documented in the form of inversion of deep-seated earlier normal faults and transpressive reactivation of a syn- to post-rift transtensional strike-slip zone, the Tápió–Tóalmás Zone (TaTZ) and related en echelon folds. The structural inversion is mainly expressed by the folding of the uppermost pre-Quaternary horizons and deformation of the surface, which suggests late Pliocene-Quaternary (∼4–0 Ma) compressional–transpressional deformation with NE–SW maximal horizontal stress axis. Drainage anomalies can be frequently connected to neotectonic structures. The uplift of the anticline hinges led to enhanced surface erosion, river piracy and development of radial drainage networks. Minor amplitude of surface undulations respective to the amplitude of folds in the upper Miocene layers reflects the syn-folding denudation of the surface during the early part of the neotectonic phase (late Pliocene to early Quaternary). On the other hand, the NW–SE-trending rectilinear features of the landscape show no tectonic control, they were shaped mostly by deflation. The combination of preliminary DEM analysis, field studies and the mapping of subsurface structural elements proved to be successful in separating landforms developed under or in absence of neotectonic control. The presence of landforms controlled by neotectonic structures suggests ongoing deformation of the Central Pannonian Basin.
