The grain content of a grain-supported sediment composed of shells can be as little as 30% of the bulk volume because the shells occupy less space than spheroids. Loose sediment is, therefore, described on the basis of the concept of mud vs. grain support. Mud refers to mud-size carbonate particles, not to mud composed of clay minerals.Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated.The influence of matrix crystallinity, chalk grain size and modification on properties of PLA/chalk composites.

The fine-grained soil is basically divided into two groups which are silt and clay.. The particles whose size ranges between 75 microns to 2 microns are known as Silt and the particles whose size smaller than 2 microns is known as clay.The chalk grain size distribution was calculated using ImageJ 1.49v software and procedure described in .

Flint occurs chiefly as nodules and masses in sedimentary …The shape of a gamma ray (or SP) log through a sand body is often thought of as a grain size profile. Three basic log shapes are recognized: funnel (coarsening upward), cylinder (blocky), and bell (fining upward) ().These three shapes can be subdivided into smooth (relatively homogeneous) or serrate (with interbedded thin shales).Chalk: 45° Clay (dry lump) 25-40° ... (C U) is a measure of gradation for the grain size distribution [114] and determined as the ratio of (D 60 /D 10); where D XX is the corresponding particle size at which XX% of the particles are smaller.
