This paper presents the results of an extensive structural investigation of the western part of the Sava Depression (SW part of the Pannonian Basin System) and provides insights in the tectonic evolution of the investigated area. Structural analyses were based on the 3D seismic volume of the study area, analysis of seismic attributes, and construction of 3D structural model and structural maps. Our results pinpoint to three tectonic phases in the structural development of the Sava Depression. The first tectonic phase is characterized by extensional tectonic features developed from the Early to Middle Miocene. The second tectonic phase follows thermal subsidence and general deepening of the study area and inherited tectonic features during the Late Miocene, while the final tectonic phase is characterized by structural reactivation and tectonic inversion of inherited and newly formed tectonic features from the Pliocene to the Quaternary.

本文介绍了萨瓦De陷西部（潘诺尼亚盆地系统西南部）的广泛结构研究结果，并为该地区的构造演化提供了见识。结构分析基于研究区域的3D地震体积，地震属性分析以及3D结构模型和结构图的构建。我们的研究结果指出了萨瓦De陷构造发展的三个构造阶段。第一构造阶段的特征是从中新世早期到中期的伸展构造特征。第二个构造阶段是在中新世晚期热沉降和研究区域普遍加深以及继承了构造特征之后，
