ABSTRACT The intersection of the Eurasian and Arabian plates and the smaller Anatolian Scholle created the Karlıova Triple Junction (KTJ) in eastern Turkey. In this study, we present analogue model experiments for this region and compare the results with our field observations and data from remote sensing imagery. Our comparison suggests that the sense of slip along curvilinear faults at the west of the KTJ changes along strike moving away from the principal displacement zones, from strike-slip to oblique normal and then to pure normal slip. Although, the active Prandtl cell model has been proposed to explain the overall regional fault pattern at eastern part of the Anatolian Scholle, the map view orientation of the secondary faults within the Karlıova wedge and performed analogue modelling results suggest that the passive wedge-shaped Prandtl cell model with a normal dip-slip component along slip lines is more appropriate in order to explain not only deformation pattern around the KTJ but also internal deformation of eastern part of the Anatolia. Moreover, these faults accumulate the significant amount of deformation that causes to the irregular earthquake behavior and the relatively lower geologic slip-rates along the main fault branch of boundary faults around the KTJ. Abbreviations: Strike-slip; Karlıova Triple Junction (KTJ); continental deformation; North Anatolian Fault Zone (NAFZ); East Anatolian Fault Zone (EAFZ);Varto Fault Zone (VFZ)

Karliova 三合点周围的上层-第四纪断层力学：对安纳托利亚 Scholle 东部变形的影响

摘要 欧亚板块和阿拉伯板块与较小的安纳托利亚 Scholle 的交汇处在土耳其东部形成了 Karlıova Triple Junction (KTJ)。在这项研究中，我们展示了该地区的模拟模型实验，并将结果与​​我们的实地观察和遥感影像数据进行了比较。我们的比较表明，沿着 KTJ 西部曲线断层的滑动感随着远离主要位移带的走向而变化，从走滑到斜法向，然后到纯正法向滑动。尽管已经提出了活动的 Prandtl 单元模型来解释 Anatolian Scholle 东部的整体区域断层模式，Karlıova 楔内次级断层的地图视图方向和执行的模拟建模结果表明，沿着滑移线具有正常倾滑分量的被动楔形 Prandtl 单元模型更合适，不仅可以解释围绕KTJ 也是安纳托利亚东部的内部变形。此外，这些断层积累了大量的变形，导致沿 KTJ 周围边界断层的主断层分支的不规则地震行为和相对较低的地质滑移率。缩写：Strike-slip; Karlıova 三联结 (KTJ)；大陆变形；北安纳托利亚断裂带（NAFZ）；东安纳托利亚断层带（EAFZ）；瓦托断层带（VFZ）这些断层积累了大量的变形，导致沿 KTJ 周围边界断层的主断层分支发生不规则地震行为和相对较低的地质滑移率。缩写：Strike-slip; Karlıova 三联结 (KTJ)；大陆变形；北安纳托利亚断裂带（NAFZ）；东安纳托利亚断层带（EAFZ）；瓦托断层带（VFZ）这些断层积累了大量的变形，导致沿 KTJ 周围边界断层的主断层分支发生不规则地震行为和相对较低的地质滑移率。缩写：Strike-slip; Karlıova 三联结 (KTJ)；大陆变形；北安纳托利亚断裂带（NAFZ）；东安纳托利亚断层带（EAFZ）；瓦托断层带（VFZ）
