- Argillolite — A consolidated argillaceous sedimentary rock, structurally formed through the cementation, compaction, and deep dehydration of fine pelitic deposits (clay muds); a fine argillaceous sandstone or mudstone rock. In a geological sense, argilolitul is characterized by a massive texture, compact mass, and the absence of obvious fissility, representing a stable lithostratigraphic unit used in sedimentary basin analysis.
