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，根据总沉积地层柱的45％至55％的不同估计。含有淤泥或粘土颗粒或粘土矿物的泥质地层可能是未元素的（硬粘土和硬粘土）或硬化的（页岩，氩，粉砂，粉砂和泥岩）。由于它们在工程特性方面的丰富性和变化，泥质岩层对岩土界（例如，基础，坡度稳定性和基础发掘）和能源部门（例如，完善，水库遏制，储层遏制和水解分裂）构成了许多挑战。
