These can be clastic sediment particles, such as clay minerals; crystals of secondary minerals, such as sylvite; or, patches of solid or liquid hydrocarbons. Crystals or massive inclusions of other evaporite minerals, such as gypsum, anhydrite, or sylvite are common.MUDSTONE. Mudstone is a fine-grained clastic sedimentary rock formed by the accumulation and consolidation of silt and clay. The clastic material forms by the weathering and breakdown of silicates to mostly clay and silt-size quartz. The small clast size (mud) commonly reflects low-energy environments of deposition. Sediment type: clastic The simplest definition is that a mudstone is a fine-grained clastic sedimentary rock that is not laminated or fissile. [5] Most definitions also include a requirement that the rock contain significant amounts of both silt- and clay-sized grains. 9.1.2.3 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 ... Black, green, and gray argillite, mudstone, and shale; graywacke, sandy limestone, tuff, and some coarse volcaniclastic rocks; chert, sandstone comprised of chert clasts, and chert pebble conglomerate; thin-bedded and massive limestone.

The difference between mudstone and shale is that mudstones break into blocky pieces whereas shales break into thin chips with roughly parallel tops and bottoms. The terms shale and claystone are sometimes used interchangeably. Siltstone The relationship between permeability and porosity for fine-grained clastic sediments (“mudstones”) is a key constitutive equation for modelling subsurface fluid flow and is fundamental to the quantification of a range of geological processes. For a given porosity, mudstone permeability varies over a range of 2–5 orders of magnitude.Quartz conglomerate.

They are vertical sheets of rock that cross-cut the horizontal layers of the badlands, like in the picture below. They are usually a different color than the surrounding rock, with tan, green, and red shades most common. These colors are caused by minerals like hematite (rust) and chlorite. Mudstone, the finest‐grained clastic rock, is not well layered, and contains more clay than does shale or siltstone. Most shales, siltstones, and mudstones are tan, brown, gray, or black.
