Arid mixed siliciclastic-carbonate coastal and marginal marine depositional systems are characterized by a high degree of complexity and internal heterogeneity. As well as complex interfingering of lithologies reflecting environmental shifts related to shoreline migration, tectonic subsidence and eustatic sea-level rise or fall these successions are strongly influenced by transient phenomena such as discharge of ephemeral rivers (and concomitant construction of short-lived deltaic successions) or the migration of aeolian dunes of various sizes through a coastal plain dominated by sabkhas and shore-parallel lagoons.

干旱混合硅质碎屑-碳酸盐海岸和边缘海相沉积体系具有高度的复杂性和内部非均质性。 除了反映与海岸线迁移、构造沉降和海平面升降有关的环境变化的复杂的岩性交指外，这些演替还受到短暂河流的排放（以及伴随的短暂三角洲演替的建设）或各种大小的风成沙丘通过以萨布哈斯和与海岸平行的泻湖为主的沿海平原的迁移等瞬态现象的强烈影响。
