Shale is considered a fissile rock … Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. A single grain can be composed of several crystals.

WebTable 6.1 The Udden-Wentworth grain-size scale for classifying sediments and the grains that make up sedimentary rocks There are six main grain-size categories; five are broken down into subcategories, with clay being the exception. The diameter limits for each successive subcategory are twice as large as the one beneath it. Sedimentary rocks form whenever these sediments are deposited and lithified and can be classified based on the size of their grains. 1. Gravel forms coarse rocks with grains over 2 mm in size. If the fragments are rounded, they form conglomerate, and if they are angular, they form breccia. 2.
