Basically, the term "mudstone" is generally used to describe a clastic sedimentary rock composed of silt and clay sized particles, with massive texture. We cannot see the difference between these rocks, but it turns out that siltstone feels gritty when nibbled or rubbed against a tooth whereas claystones feel smooth. The streak of Shale and Mudstone is … Shale and mudstone are both widely used terms for fine-grained terrigenous clastic rocks (although some use fissility as a requirement for the use of the term “shale”), but there is at present no broadly agreed upon terminology for naming and classifying these rocks (see discussions in Schieber et al., 1998, and Potter et al., 2005).
