Click on image to see enlarged photo.Sedimentary rock - Clastic, Chemical, Organic: The texture of a sandstone is the sum of such attributes as the clay matrix, the size and sorting of the detrital grains, and the roundness of these particles. To evaluate this property, a scale of textural maturity that involved four textural stages was devised in 1951. These stages are described as follows.
