WebJun 5, 2012 · Sedimentary texture encompasses three fundamental properties of sedimentary rocks: grain size, grain shape (form, roundness, and surface texture [microrelief] of grains), and fabric (grain packing and orientation). Grain size and shape are properties of individual grains. Fabric is a property of grain aggregates.
