===Texture (Grain Size)===

Textural analysis (grain size, shape, orientation of individual grains, and overall sorting) provides insights into (1) sediment provenance, (2) proximity to sediment supply points, (3) water column energy level, and (4) rock properties such as porosity and permeability.
