Abstract The Beni Suef Basin is a rift basin that was formed in the Early Cretaceous in response to the break-up of the Gondwana. The infill consists of a thick Mesozoic–Paleogene succession deposited during two main tectonic phases; the Early Cretaceous syn-rift phase and the Late Cretaceous post-rift phase. The post-rift phase was subsequently subjected to an intense compressional tectonic regime related to late Cretaceous Syrian arc tectonics. Within the basin-fill succession, the Senonian deposits, which are composed of carbonates and mixed siliciclastic/carbonate rocks of the “B” and “A” members of the Abu Roash Formation, was formed as a marine platform developed under fluctuated shelfal conditions. These deposits were overlain by chalk of the Khoman Formation that is interpreted to have formed in an outer shelf–middle slope setting. The Senonian succession is subdivided into two 3rd order depositional sequences (Latest Turonian–Early Coniacian SQ-1 and Coniacian–Santonian SQ-2) and one 2nd order depositional sequence (Campanian–Maastrichtian SQ-3). The depositional history of the Senonian in the Beni Suef Basin is interpreted to have been controlled by variable sedimentation accompanied by progradation and retrogradation of carbonate platform between inner and outer shelf environments during the Coniacian–Santonian, and between inner shelf and upper slope environments during the Campanian–Maastrichtian to the end of Senonian. The changes in depositional environments and relative sea-level fluctuations were a factor of the variations in accommodation and sedimentation likely controlled primarily by the Syrian Arc tectonic pulses, which may also have affected basin development and that of the surrounding areas over the northern Western Desert of Egypt particularly during Senonian.

受构造影响的叙利亚弧沉积带的塞诺阶地台-斜坡演化：埃及贝尼苏夫盆地

摘要 贝尼苏夫盆地是早白垩世为响应冈瓦纳纪断裂而形成的裂谷盆地。填充物由在两个主要构造阶段沉积的厚中生代-古近系层序组成；早白垩世同裂谷期和晚白垩世后裂谷期。裂谷后阶段随后受到与晚白垩世叙利亚弧构造相关的强烈挤压构造体制。在盆地填充层序中，由阿布罗阿什组“B”和“A”段的碳酸盐和混合硅质碎屑/碳酸盐岩组成的 Senonian 沉积物形成为在波动的陆架条件下发育的海相台地。这些沉积物被 Khoman 组的白垩覆盖，被解释为形成于外陆架-中斜坡环境中。Senonian 层序被细分为两个三级沉积层序（最新土伦阶-早期康涅狄格 SQ-1 和康尼亚阶-桑托阶 SQ-2）和一个二级沉积序列（坎帕阶-马斯特里赫特 SQ-3）。Beni Suef 盆地 Senonian 的沉积历史被解释为在 Coniacian-Santonian 期间内陆架环境和外陆架环境之间以及内陆架和上斜坡环境之间伴随着碳酸盐台地前积和后退的可变沉积控制。坎帕阶-马斯特里赫特阶到森诺阶末期。沉积环境的变化和相对海平面波动是可能主要由叙利亚弧构造脉冲控制的住宿和沉积变化的一个因素，
