Breccia is generally comprised of 30% or more of rock fragments measuring more than 2 mm in size, with sand, silt, and clay making up the remainder of the rock volume. These grains are cemented together by silica, calcite, or iron oxide. The rock fragments can be made of any previously existing rock (s).

Secondary characteristics used to further distinguish clastic rocks are sorting, grain shape, and grain composition. Grain size: Clastic sediments are distinguished on the basis of average grain size. gravel-size particles are larger than 2 mm diameter sorting. Sedimentary rocks composed of mostly but not all stable minerals would be considered: submature. Which grain size is found in argillite terrigenous rocks? silt/clay. Which grain size is found in rudite terrigenous rocks? gravel. Rock fragments are considered unstable. True.Grain Size. Detrital rock is classified according to sediment grain size, which is graded from large to small on the Wentworth scale (see figure).Grain size is the average diameter of sediment fragments in sediment or rock. Grain sizes are delineated using a logbase-2 scale [9; 10].For example, the grain sizes in the pebble class are 2.52, 1.26, 0.63, 0.32, 0.16, and 0.08 inches, which ...
