Chalk grain size.

Chalk, soft, fine-grained, easily pulverized, white-to-grayish variety of limestone. Chalk is composed of the shells of such minute marine organisms as foraminifera, coccoliths, and rhabdoliths. The purest varieties contain up to 99 percent calcium carbonate in the form of the mineral calcite.

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 is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite.

Oolitic limestone is composed of small spherical grains known as oolites that may have a concentric structure. Oolites range in size up to 2 mm in diameter and form by the precipitation of calcite around a grain nucleus composed of another particle or shell.The Dixie Belle Paint Company recommends two coats to ensure durability and protection from bleed-through, water, grease and mold. Regular chalk paint has no built-in protection from grease, water, or mold. This Dixie Belle Silk Mineral paint also has a built-in topcoat. But the finish is definitely eggshell and not satin or shiny.The grain size and composition of minerals in shale determine its permeability, hardness, and plasticity. In general, shale is fissile and readily splits into layers parallel to the bedding plane, which is the plane of clay flake deposition. Shale is laminated, meaning the rock consists of many thin layers that are bound together.What is the grain size of chalk rock? Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles. In many cases, the grains are microscopic fragments of fossil animal shells.
