The uppermost Albian–Turonian interval has been studied in the south of the Izeh Zone (SW Iran) to investigate the depositional history of the Sarvak Formation in this area. This interval in the Middle East is characterized by the presence of very large shallow water carbonate platforms, surrounding the intra-shelf basins. The expansion of up to 90% hemipelagic strata throughout the studied outcrop proposes that it has been deposited in an intra-shelf basin. Three Cenomanian and one Turonian depositional sequences were distinguished in the studied interval based on the alternation of three microfacies associations including oligosteginid-dominated, oligosteginid-free, and platform-top microfacies. The biostratigraphical calibration by means of the planktic foraminifera indicates that these sequences can be well correlated on a global scale. The simultaneous influence of eustatic, tectonic, and environmental factors on the depositional sequences in the Lar Anticline section makes it difficult to identify the dominance of one over the others. The ability to correlate the sequence boundaries in the studied section with the global events suggests the effect of eustasy on the deposition of this interval. However, the tectonic control by the creation of a paleo-depression, subsidence (during the TST of Sequence 3), and uplift (at the Cenomanian/Turonian boundary (SB4) and mid-Turonian (SB5)) overprinted the eustatic factor. The influx of clay and the black shale formation during OAE2 conditions are the environmental factors that cannot be ignored in the deposition of sequence 1 and sequence 3, respectively.

在伊泽（Izeh）地区（伊朗西南部）的南部，已经研究了最上层的阿尔比一突厥间期，以研究该地区萨尔瓦克组的沉积历史。中东的这种间隔期的特征是围绕陆架内盆地存在着很大的浅水碳酸盐台地。在整个研究露头中，高达90％的半流层地层扩张表明它已沉积在一个陆架内盆地中。基于三个微相关联的交替，区分了三个塞诺曼期和一个Turonian沉积层序，这些微相包括低位硬胶体为主，无低位胶体和平台顶部微相。通过浮游有孔虫的生物地层学标定表明，这些序列在全球范围内可以很好地相关。在拉尔背斜剖面中，喜人，构造和环境因素对沉积序列的同时影响使得很难确定一个在另一个之上的优势。将研究部分中的序列边界与全局事件相关联的能力表明，迷魂药对此间隔的沉积有影响。但是，通过构造古凹陷，下沉（在序列3的TST期间）和隆升（在Cenomanian / Turonian边界（SB4）和Turonian中部（SB5））进行的构造控制覆盖了欣喜因素。OAE2条件下粘土的涌入和黑色页岩的形成是分别在序列1和序列3沉积中不能忽略的环境因素。而且，Lar Anticline部分中沉积序列上的环境因素使得很难确定一个在另一个上的优势。将研究部分中的序列边界与全局事件相关联的能力表明，迷魂药对此间隔的沉积有影响。但是，通过构造古凹陷，下沉（在序列3的TST期间）和隆升（在Cenomanian / Turonian边界（SB4）和Turonian中部（SB5））进行的构造控制覆盖了欣喜因素。在OAE2条件下，粘土的涌入和黑色页岩的形成分别是序列1和序列3沉积中不可忽视的环境因素。而且，Lar Anticline部分中沉积序列上的环境因素使得很难确定一个在另一个上的优势。将研究部分中的序列边界与全局事件相关联的能力表明，迷魂药对此间隔的沉积有影响。但是，通过构造古凹陷，下沉（在序列3的TST期间）和隆升（在Cenomanian / Turonian边界（SB4）和Turonian中部（SB5））进行的构造控制覆盖了欣喜因素。OAE2条件下粘土的涌入和黑色页岩的形成是分别在序列1和序列3沉积中不能忽略的环境因素。将研究部分中的序列边界与全局事件相关联的能力表明，迷魂药对此间隔的沉积有影响。但是，通过构造古凹陷，下沉（在序列3的TST期间）和隆升（在Cenomanian / Turonian边界（SB4）和Turonian中部（SB5））进行的构造控制覆盖了欣喜因素。OAE2条件下粘土的涌入和黑色页岩的形成是分别在序列1和序列3沉积中不能忽略的环境因素。将研究部分中的序列边界与全局事件相关联的能力表明，迷魂药对此间隔的沉积有影响。但是，通过构造古凹陷，下沉（在序列3的TST期间）和隆升（在Cenomanian / Turonian边界（SB4）和Turonian中部（SB5））进行的构造控制覆盖了欣喜因素。在OAE2条件下，粘土的涌入和黑色页岩的形成是分别在序列1和序列3沉积中不能忽略的环境因素。隆起（在Cenomanian / Turonian边界（SB4）和Turonian中部（SB5））套印了欣喜因子。OAE2条件下粘土的涌入和黑色页岩的形成是分别在序列1和序列3沉积中不能忽略的环境因素。隆起（在Cenomanian / Turonian边界（SB4）和Turonian中部（SB5））覆盖了欣喜因子。OAE2条件下粘土的涌入和黑色页岩的形成是分别在序列1和序列3沉积中不能忽略的环境因素。
