Modified date: 23/04/2023. Mudstone is a really pleasant-grained sedimentary rock consisting of a aggregate of clay and silt-sized particles. Terms including claystone and siltstone are often used in location of mudstone, although these consult with rocks whose grain length falls inside a good deal narrower stages and underneath near exam those ...Fair-sorted rocks contain 75 to 90 percent silt or clay. Poorly sorted siltstone or claystone contains less than 75 percent silt or clay. If fissile, fine-grained clastic rocks are so designated. The mineral composition of most fine-grained clastic rocks can be determined reliably with the petrographic microscope and by X-ray diffraction.Sedimentary Rocks.

Fine-Grained Clastic Rocks. Rock composed of at least 75% silt- and clay-sized clasts is called mudrock (Figure 9.5, bottom row). If a mudrock shows evidence of fine layers (laminations) and breaks into sheets, it is called shale. Otherwise, it is siltstone (dominated by silt), mudstone (a mix of silt and clay), or claystone (dominated by clay).

Clastic sedimentary rocks are classified by size of the sediment particles making up the rock. Particle size descriptions like sand, silt, and clay have specific meaning in geology and engineering. (see chart below). Shales, mudstones and claystones are rock types that are very similar to each other.
