| Notenote | Use of 'dectable silt' in the criteria for this category is based on the observation that in practice, distinction of claystone from 'siltstone' is typically based on a qualitative assessment of 'grittiness' (e.g. rubbing with fingers, or chewing); the property that these tests can determine is the presence or absence of silty particles in the material. Quantitative grain size analysis in the the clay/silt fraction of a lithified sediment is difficult at best, and of questionable significance because diagensis has altered the size and mineralogy of original sedimentary particles. |
