Angularity is difficult to quantify. Powers (1953) has proposed a classification system based on a visual examination of the grains and a comparison with a roundness scale (see Appendix B). 

As the precipitation of carbonates from the pore water is very sensitive to variables like porosity, permeability, texture and composition of the fill mass, the water depth, temperature and chemistry of the pore water and the burial depth, the resulting cementation may be highly variable as well, both in terms of strength and in terms of spatial distribution (vertical and lateral extent).
