High‐resolution stratigraphical architecture of a Quaternary fluvial succession in the Makó Trough and the Danube‐Tisza Interfluve (Pannonian Basin, Hungary) was investigated based on low field magnetic susceptibility (MS) measurements of seven fully cored boreholes, interpreted on the basis of the early postglacial magnetic susceptibility episodes previously described in the Körös and Jászság Basins. To confirm the reliability of the Dévaványa and Vésztő MS records (Körös Basin), the published magnetostratigraphical data were re‐investigated revealing the consequent arrangement of the MS peaks correlated with the Jingbian section and the short‐lived polarity reversals correlated with the Geomagnetic Instability Time Scale. The Quaternary climatic regime in the Körös Basin begins in the late Pliocene at 2.7 Ma. The correlation between the Körös Basin (Dévaványa) and Makó Trough (Mindszent) was confirmed by the multi‐proxy spectral investigation of the Mindszent section, revealing ~100‐ and ~41‐ka cycles in the MS, colour, logged spontaneous potential and resistivity records. Based on MS records of the seven boreholes, the base of the Quaternary can be identified irrespective of the facies, age and climatic phase of the lowermost Quaternary strata. By performing MS and log correlation of 131 boreholes, extended unconformities were detected in the Quaternary profiles in the Danube‐Tisza Interfluve (~1070±10, ~1920±10 and ~2300±10 ka) interpreted as sequence boundaries. Sedimentological and mineralogical data reveal a significant change at ~725–606 ka likely as a response to the ‘mid‐Pleistocene transition’, leading to the multiple branching of the Danube. SEM data revealed that ilmenite is also responsible for the development of the early postglacial magnetic susceptibility episodes. This increases the stratigraphical potential of fluvial successions with catchment area that contain metamorphic rocks. A gradual retreat of permafrost zone determines long‐term temporal trends of the climatically controlled fluvial magnetic susceptibility episodes, causing upward decreasing trends in the time series.

基于磁化率数据的匈牙利马科海槽和多瑙河-蒂萨河际流第四纪河流相沉积物的高分辨率地层学

基于七个完全取芯的钻孔的低场磁化率（MS）测量结果，研究了马科海槽和多瑙河-蒂萨河际流（匈牙利潘诺尼盆地）第四纪河流相演替的高分辨率地层构造。冰河早期的磁化率早期发作，以前在Körös和Jássság盆地中有过描述。为了确认Dévaványa和VésztőMS记录（科尔斯盆地）的可靠性，重新调查了已公布的地磁数据，揭示了与靖边剖面相关的MS峰的后续排列以及与地磁不稳​​定时间相关的短时极性反转。规模。Körös盆地的第四纪气候始于上新世晚期，距今2.7 Ma。Mindszent剖面的多代理光谱研究证实了Körös盆地（Dévaványa）和MakóTrough（Mindszent）之间的相关性，揭示了MS的〜100和〜41ka周期，颜色，测得的自发电势和电阻率记录。根据七个钻孔的MS记录，可以确定第四纪的基底，而与最低第四纪地层的相，年龄和气候阶段无关。通过对131个钻孔进行MS和测井相关性分析，在多瑙河-Tisza Interfluve（〜1070±10，〜1920±10和〜2300±10 ka）的第四纪剖面中发现了扩展不整合面，被解释为层序边界。沉积学和矿物学数据显示，在大约725-606 ka处发生了显着变化，可能是对“中更新世过渡”的响应，导致了多瑙河的多分支。扫描电镜数据表明，钛铁矿也是冰川后早期磁化率事件发展的原因。这增加了包含变质岩的集水区河流相演替的地层潜力。多年冻土带的逐渐退缩决定了受气候控制的河流磁化率事件的长期时间趋势，从而导致时间序列呈下降趋势。
