Graywacke is a type of sandstone characterized by its coarse texture and composition, typically consisting of a mix of sand-sized grains, mud, and rock fragments. It forms primarily in tectonically active environments, often through the rapid deposition of sediment in deep marine settings, such as submarine fans or turbidite systems. The mixture of different particle sizes and the presence of clay matrix give graywacke its distinctive appearance and properties. Over time, lithification processes, including compaction and cementation, solidify the sediments into rock.
