Sediment Grain Size Chart for Rocks - ThoughtCo
See more on thoughtco.comSediments are classified by their method of erosion as either clastic or chemical. Chemical sediment is broken down through chemical weathering with transportation, a process known as corrosion, or without. That chemical sediment is then suspended in a solution until it precipitates. Think of what happens to a gl…- Published: Feb 14, 2009

Grain size – Geology is the Way
Grain size is the average diameter of clasts (particles) of clastic sediments and rocks. Grain size is the primary parameter in sedimentary geology to divide clastic rocks and sediments in different classes for classification purposes.
