Argillaceous formations are the most abundant sedimentary soil and rock types, varying according to different estimates from 45 to 55% of the total sedimentary formation column. The argillaceous formations containing silt- or clay-sized particles or clay minerals could be uncemented (stiff clays and hard clays) or hardened (shales, argillites, siltstones, and mudstones). Due to their abundance and variation in engineering properties, the argillaceous formations impose many challenges on the geotechnical community (e.g., foundation, slope stability, and underground excavation) and energy sector (e.g., well completion, reservoir containment, and hydraulic fracturing).

泥质地层是最丰富的沉积土壤和岩石类型，根据不同的估计，占总沉积地层柱的45%至55%。含有粉砂或粘土大小颗粒或粘土矿物的泥质地层可能是未胶结的（硬粘土和硬粘土）或硬化的（页岩、泥质岩、粉砂岩和泥岩）。由于其丰富性和工程性质的变化，泥质地层对岩土工程界提出了许多挑战（例如，地基、边坡稳定性和地下开挖）和能源部门（例如，完井、储层封闭和水力压裂）。
