The Başkale Basin is located in the easternmost part of Türkiye, within a tectonically active area, and located at the intersection of Europe, Asia and the Middle East. In this study, the Dereiçi travertines, one of the most important products of neotectonism in the basin, were investigated sedimentologically, mineralogically and geochemically. To understand the neotectonic evolution of the travertine succession, the sequence was studied from bottom to top as regards morphology, lithofacies and U/Th dates. Crystalline crust, coated gas bubbles, shrub, paper-thin raft and palaeosol lithofacies have been detected in the Dereiçi travertines, which are morphologically of layer type, two ridge types and terrace type. The Dereiçi travertines commenced to precipitate at the intersection of the Işıklı and Ilıcak faults at 255.56 ±9.01 ka, and their deposition continues today. Travertine deposition paused twice between 198.31 ±18–143.07 ±1.5 ka and 96.73 ±8.34–61.59 ±5.4 ka, when palaeosol development took place. According to field and laboratory studies, the Dereiçi travertines developed under climate and tectonic control. The Işıklı and Ilıcak faults played active roles in the development of the travertines. As the travertine ages are linked to movement on both faults, the age of the Işıklı Fault should be 255.56 ±9.01 ka or earlier, and that of the Ilıcak Fault should be 143.07 ±1.5 ka or earlier.

巴斯卡勒盆地位于土耳其最东端，地处构造活跃区，地处欧亚中东交汇地带。在这项研究中，Dereiçi 石灰华是该盆地新构造运动最重要的产物之一，我们对其进行了沉积学、矿物学和地球化学研究。为了了解石灰华层序的新构造演化，从下到上研究了层序的形态、岩相和 U/Th 年代。在Dereiçi钙华中发现结晶地壳、包覆气泡、灌木、薄纸筏和古溶胶岩相，形态呈层状、二脊状和阶地状。在 255.56 ±9.01 ka，Dereiçi 石灰华开始在 Işıklı 和 Ilıcak 断层的交汇处沉淀，他们的证词今天仍在继续。石灰华沉积在 198.31 ±18–143.07 ±1.5 ka 和 96.73 ±8.34–61.59 ±5.4 ka 之间停顿了两次，此时古土壤开始发育。根据实地和实验室研究，Dereiçi 石灰华是在气候和构造控制下形成的。Işıklı 和 Ilıcak 断层在石灰华的发育过程中发挥了积极作用。由于钙华年龄与这两个断层的运动有关，因此 Işıklı 断层的年龄应为 255.56 ±9.01 ka 或更早，而 Ilıcak 断层的年龄应为 143.07 ±1.5 ka 或更早。Işıklı 和 Ilıcak 断层在石灰华的发育过程中发挥了积极作用。由于钙华年龄与这两个断层的运动有关，因此 Işıklı 断层的年龄应为 255.56 ±9.01 ka 或更早，而 Ilıcak 断层的年龄应为 143.07 ±1.5 ka 或更早。Işıklı 和 Ilıcak 断层在石灰华的发育过程中发挥了积极作用。由于钙华年龄与这两个断层的运动有关，因此 Işıklı 断层的年龄应为 255.56 ±9.01 ka 或更早，而 Ilıcak 断层的年龄应为 143.07 ±1.5 ka 或更早。
