Abstract Integrated foraminiferal and geochemical analyses of the upper Maastrichtian-lower Danian succession of the Gebel Tawil Shihaq section in the Central Jordan Plateau has been conducted to interpret the nature of that succession within a sequence stratigraphic context. The studied succession covers the interval of the CF4-P1c planktonic foraminiferal zones. The incorporation of foraminiferal and geochemical proxies led to the recognition of four 3rd order depositional sequences, three in the Maastrichtian (M-Sq1, M-Sq2, and M-Sq3) and one in the Danian (D-Sq1). These depositional sequences are bounded by four sequence boundaries, detected based on abrupt faunal (e.g., zonal interruption, foraminiferal turnover) and geochemical (e.g., dolomitization, Sr/Ca and nearby Ti/Al maxima, Mn and CaCO3 minima) shifts. Based on the paleodepth variation revealed from the foraminiferal analyses and the consistent behavior of the different geochemical proxies, a relative sea-level curve was established and consequently, the systems tracts of each depositional sequence were recognized. The development of the inferred relative sea-level curve reveals the twofold control of both global sea-level changes and regional tectonics. The latter resulted in amalgamation and elimination or modification of some sea-level cycles relative to the previously recognized eustatic schemes. At the Cretaceous/Paleogene (K/Pg) boundary, a highly agitated phosphatized event bed is intercalated and exposes distinctive unique lithological, geochemical, and biostratigraphical characteristics denoting a long-lasting period of non-deposition and erosion commonly interrelated to the tectonic impact of the Syrian Arc Orogeny (SAO).

约旦中部 Gebel Tawil Shihaq 的晚马斯特里赫特-早大年海平面变化：化学地层学和有孔虫生物地层学的意义

摘要 对约旦中部高原 Gebel Tawil Shihaq 剖面的上马斯特里赫特 - 下大年序列进行了综合有孔虫和地球化学分析，以在层序地层背景下解释该序列的性质。研究的演替涵盖了 CF4-P1c 浮游有孔虫区的间隔。有孔虫和地球化学代理的结合导致识别出四个三级沉积序列，三个在马斯特里赫特（M-Sq1、M-Sq2 和 M-Sq3），一个在大年（D-Sq1）。这些沉积层序以四个层序边界为界，根据突然的动物区系（例如，地带性中断、有孔虫的更新）和地球化学（例如，白云石化、Sr/Ca 和附近的 Ti/Al 最大值、Mn 和 CaCO3 最小值）变化进行检测。基于有孔虫分析揭示的古深度变化和不同地球化学代理的一致行为，建立了相对海平面曲线，从而识别了每个沉积序列的系统域。推断的相对海平面曲线的发展揭示了全球海平面变化和区域构造的双重控制。后者导致合并和消除或修改与先前公认的eustatic 方案相关的一些海平面周期。在白垩纪/古近纪 (K/Pg) 边界处，一个高度搅动的磷化事件床被插入并暴露出独特的岩性、地球化学、
