Passive margins are traditionally regarded as tectonically quiescent, however the increasing recognition of significant post-rift tectonic uplift along their flanks offers an important control on sediment delivery. The most extensive record of the early post-rift succession of the Central Atlantic Margin (CAM) is found in the Lower and Middle Jurassic outcrops of the Essaouira-Agadir Basin (EAB). This important succession is characterised by alternating deposition of marine carbonates and paralic siliciclastics that correlate with periods of tectonic activity along the margin, rejuvenating sediment input to the basin. Field observations, well data and petrographic analysis are integrated into a coherent sedimentological model, correlated across the basin within a sequence stratigraphic framework. Comparison is drawn with equivalent dated units in the Central High Atlas, which allows a constraint on the regional versus local tectonostratigraphic evolution.

In the EAB, Upper Sinemurian to Lower Pliensbachian open marine ramp carbonates record an initial transgression. They are only preserved locally in the north of the basin, below a major fluvial erosion surface that is regionally traceable across the basin and incisive into the Pliensbachian, CAMP basalts or Triassic sediments. In the Central High Atlas (CHA), the correlative fluvial erosive event has been dated as Toarcian in age. This influx of siliciclastic sediments is interpreted to have been sourced from the Meseta and/or the Anti-Atlas, supporting recent apatite-fission track thermochronology that indicates erosional exhumation at this time.

During the Upper Toarcian, a regional carbonate platform, dominated by peritidal deposits, developed across the EAB in response to renewed marine transgression. Facies include oolitic and bioclastic grainstones, crystalline dolomite, stromatolites and dissolution breccias or evaporites. Overlying Middle Jurassic shallow-marine and fluvial siliciclastics encroached from south of the basin (possibly related to a potential source area in the Anti-Atlas), while to the north shallow marine carbonates dominated. These observations evidence the role of tectonic movements of the hinterland during a passive margin phase as a mechanism to trigger forced regressions, compensating the effect of eustasy.

被动边缘在传统上被认为是构造上的静止，但是，人们越来越认识到裂谷后沿其侧面的明显构造隆升为沉积物的输送提供了重要的控制。最早的裂谷后中大西洋边缘（CAM）演替的最广泛记录是在索维拉-阿加迪尔盆地（EAB）的侏罗纪中下部露头。这一重要演替的特征是海相碳酸盐岩和准硅质碎屑岩交替沉积，这与沿边缘的构造活动周期有关，使输入到盆地的沉积物重新焕发活力。现场观测，井数据和岩石学分析被整合到一个连贯的沉积学模型中，并在一个层序地层学框架内与整个盆地相关联。

在EAB中，上Sinemurian至Lower Pliensbachian的开放性海洋斜坡碳酸盐岩记录了一次海侵。它们仅保留在盆地北部的局部主要河流侵蚀面以下，该河流在整个盆地上都可以追溯到，并切入Pliensbachian， CAMP玄武岩或三叠纪沉积物中。在中部高级地图集（CHA）中，相关河流侵蚀事件的年龄已定为Toarcian。硅质碎屑沉积物的这种涌入被认为是从梅塞塔和/或反图集获得的，这支持了最近的磷灰石裂变径迹热年代学，表明此时的侵蚀性掘出。

在上Toarcian期间，响应新的海侵，整个EAB形成了一个以碳酸盐沉积为主的区域性碳酸盐台地。岩相包括鲕粒和生物碎屑岩，结晶白云岩，叠层石和溶解角砾岩或蒸发岩。盆地南部（可能与Anti-Atlas的潜在源区有关）侵占了上侏罗统浅海和河流硅质碎屑岩，而北部则占据了浅海碳酸盐岩。这些观察结果证明了被动边缘期腹地构造运动作为触发强迫回归，补偿摇头丸效应的机制的作用。
