screenings
n.pl.— «Screenings are another name for fines. These fines range in dimension from dust-sized particles to small, angular rock chips no bigger than a pencil eraser. They are a byproduct of the rock-crushing process and are a very important component for the patio’s base material.» —“Flagstone patios benefit from secure base” by Tim Carter Indianapolis Star (Ind.)
