This qualitative and quantitative study describes the evolution of water–rock interaction processes in the groundwater–seawater mixing zone diagenetic environment associated with the development of sand injectite outcrops of the Bahrah coastal plain, northern Kuwait Bay. Fourteen rock samples were collected from the field area for petrographic analyses, X-ray diffractometry (XRD), transmitted-light microscopy (TLM), tungsten scanning electron microscopy (SEM), and cold cathodoluminescence (CL). Two groundwater samples were used for geochemical studies of bulk water chemistry properties (12 ions and salinities) and water isotope data (δ³⁴S, δ³⁷Cl, δ⁸¹Br, and δ¹³C of dissolved inorganic carbon, DIC). We found that in the mixing zone, 70% groundwater mixes with 30% seawater at shallow depths, which controls the diagenetic processes highlighted by the variability of petrographic characteristics of sand injectites in the study area.

这项定性和定量研究描述了与科威特湾北部 Bahrah 沿海平原喷砂岩露头的开发相关的地下水-海水混合区成岩环境中水-岩相互作用过程的演变。从现场区域收集了 14 个岩石样品，用于岩相分析、X 射线衍射 (XRD)、透射光显微镜 (TLM)、钨扫描电子显微镜 (SEM) 和冷阴极发光 (CL)。两个地下水样品用于大量水化学性质（12 个离子和盐度）和水同位素数据（δ ³⁴ S、δ ³⁷ Cl、δ ⁸¹ Br 和 δ ¹³C 溶解的无机碳，DIC)。我们发现在混合带中，70% 的地下水与 30% 的浅层海水混合，这控制了研究区注砂岩岩相特征的变异性所突出的成岩过程。
