sedimentid
Sedimentid refers to a broad category of sedimentary rocks that are classified based on their grain size. This classification system, commonly used in geology, distinguishes between different types of clastic sedimentary rocks. The primary factor determining a rock's sedimentid classification is the average diameter of the individual mineral or rock fragments that make up the rock.
The coarsest sedimentids are conglomerates and breccias. Conglomerates consist of rounded pebbles and cobbles, indicating that
Sandstones are the next largest sedimentid, formed from sand-sized grains, typically between 0.0625 and 2 millimeters
The finest sedimentids are shales and mudstones, both made up of clay-sized particles, which are less than
