Hauterivian–Barremian deposits, outcropping in central Tunisia, consist of varied deposits. A detailed study pertaining to field prospecting and facies investigation yielded 15 facies, grouped into three lithofacies associations: siliciclastic, carbonates, and mixed series. These lithofacies were settled on varied shallow marine environments. Meter-scale shallowing up sequences passing up from lower infratidal to supratidal environments recorded the regressive trend of the Bou Hedma Formation. Facies panoply and stacking patterns show the control of both climate and tectonics. Synsedimentary tectonics and diapirism controlled the accommodation space. High subsidence rates allowed the accumulation of massively bedded evaporites, especially for the uppermost part. The turnover from humid to xeric conditions yielded the conspicuous change in sedimentary fabrics. The record of sebkha sequences, within the upper Bou Hedma Formation, points to the occurrence of containment conditions and the cease of huge detrital inputs. From south to north, the gradual transition from barren shallow marine environments to ammonite-rich deeper tiers is summarized in a tectonically disturbed mixed-series ramp, occasionally submitted to storms. A correlative study across the Tethyan realms proved that the deepest deposits, cropping out in northeastern Tunisia, could represent lateral equivalents of the Vocontian (France) and the Rio Argos (Spain) hemipelagic ammonite-rich carbonates and marls. Subtropical warm and xeric Suitable paleoenvironmental conditions allowed the occurrence of rudist-coral-bryozoan buildups in east-central Tunisia. These deposits could be coeval to the “urgonien blanc” reefs prospering in northern Tethyan realms. Fault reactivation associated with halokinetic movements triggered mass-gravity deposits hampering builders to thrive.

在突尼斯中部露头的上特韦尔－巴雷米亚矿床由各种矿床组成。有关现场勘探和相调查的详细研究产生了15个相，分为三个岩相协会：硅质碎屑岩，碳酸盐岩和混合系列。这些岩相沉积在各种浅海环境中。从下层下层环境上升到上层环境的米级浅层上升序列记录了布·赫德玛组的回归趋势。全景相和堆积模式显示了对气候和构造的控制。同沉积构造和底辟作用控制着居住空间。高沉降率使大量的层状蒸发物聚集，特别是在最上部。从潮湿到干燥条件的周转产生了沉积织物的显着变化。上布赫德玛组内的sebkha序列记录指出了围堵条件的发生和大量碎屑输入的停止。从南到北，从构造受扰动的混合系列斜坡中总结出了从贫瘠的浅海环境到富氨铁矿深层的逐渐过渡，该斜坡偶尔会遭受暴风雨的侵袭。跨Tethyan领域的相关研究证明，突尼斯东北部最深的沉积物可能代表了Vocontian（法国）和Rio Argos（西班牙）的富含半褐铁矿的碳酸盐和泥灰岩的侧向等价物。亚热带温暖和干燥的适当的古环境条件允许突尼斯中东部发生红绿柱石-珊瑚-苔藓虫堆积。这些沉积物可能与特提斯北部地区蓬勃发展的“乌贡白滩”珊瑚礁相提并论。伴随着运动运动的断层再激活触发了重力沉积，阻碍了建造者的蓬勃发展。
