Siliciclastic

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.
