Cross beds in siliciclastic shoreface sediment (Agadir-Essaouira Basin, Morocco)

Siliciclastic (or siliclastic[1]) rocks are clastic noncarbonate sedimentary rocks that are composed primarily of silicate minerals, such as quartz or clay minerals. Siliciclastic rock types include mudrock, sandstone, and conglomerate.[1][2]

Siliciclastic sediments are silica-based sediments, lacking carbon compounds, which are formed from pre-existing rocks, by breakage, transportation and redeposition to form sedimentary rock.[3]
