Silt is commonly found in suspension in river water, and it makes up over 0.2% of river sand. It is abundant in the matrix between the larger sand grains of graywackes.

This sand type forms in tropical waters through precipitation , sedimentation , and microbial activity, and is indicative of high energy environments. [ 1 ]
