Classification of Mudstone. Photo by W. W. Little Mudstone is defined as a clastic sedimentary rock in which the ratio of mud when mixed with sand is at least 50% and when mixed with gravel is at least 70%. Mudstones are classified first by grain size and second by fissility.

5.3.1 Lithification and Diagenesis. Lithification turns loose sediment grains, created by weathering and transported by erosion, into clastic sedimentary rock via three interconnected steps. Deposition happens when friction and gravity overcome the forces driving sediment transport, allowing sediment to accumulate.is that containing mainly clastic grains (SN-type mudstone).

The area of clastic rocks is 108,972 km 2, which is about 46.04% area of Guangxi (Fan 2015). The clastic rock slopes are mainly composed of thin and weak layers of medium-thickness rocks, and soft rocks are mostly mudstones with thickness varying from several centimeters to several meters.

Clastic Sedimentary Rocks: Clastic sedimentary rocks are the group of rocks most people think of when they think of sedimentary rocks. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. deposited are called clastic rocks. Clasts are the fragments of rocks and minerals. Examples of clastic rocks are sandstone and mudstone. Non-clastic rocks are created when water evaporates or from the remains of plants and animals. Limestone is a non-clastic sedimentary rock. 3 Clastic sedimentary rocks are classified by the shape of their ... Texture - clastic (only noticeable with a microscope). Grain size - very fine-grained (< 0.06mm); clasts not visible to the naked eye. Hardness - generally quite soft, but can be hard and brittle.
