Sedimentary rocks with names

Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most …

Well-established rock names are retained wherever possible, although some terms are more rigorously defined. The scheme is essentially hierarchical. Rock names are assigned using a system of approved root terms and qualifier terms. Explanatory notes. The names and descriptions used in the RCS are derived from a series of reports written by BGS ... Chert is a hard and compact sedimentary rock, consisting dominantly of very small quartz crystals. Chert occurs mostly in carbonate sedimentary rocks as nodules or layers. Flint is a dark-colored variety of chert.^ Coal is a combustible rock containing more than 50% by weight of carbonaceous material. Coal in most cases is a lithified peat.For example, if an igneous intrusion goes through a series of metamorphic rocks, the intrusion must be younger than the metamorphic rocks that it cuts through (Figure 11.12). The Grand Canyon provides an excellent illustration of Steno’s laws. Figure 11.13 shows the many horizontal layers of sedimentary rock that make up the canyon.Figure 4.4 –Examples of igneous rocks with different grain sizes and color from pegmatite to glass.

There are sizable deposits of oil shale around the world, particularly in the western United States, Australia, Brazil, and parts of Europe.C. Metamorphic Rock Names Field names for metamorphic rocks are less logical, simple, and consistent than names for other rock types.

A few geologists use the word "quartzite" for sedimentary rocks that have an exceptionally high quartz content. This usage is falling out of favor but remains in older textbooks and other older publications. The name "quartz arenite" is a more appropriate and less confusing name for these rocks.

As the name suggests, Sedimentary Rocks are composed of sediments that have been cemented and compacted together, or lithified , over long periods of time.Those from ash falls are often well layered and look like fine-grained sedimentary rocks. The terms for rock composition and size can be combined in the rock name. Common examples are lithic lapilli tuff, crystal tuff and dacitic vitric tuff.

Sedimentary rocks are the most common rocks exposed on Earth’s surface but are only a minor constituent of the entire crust, which is dominated by igneous and metamorphic rocks. Sedimentary rocks are produced by the weathering of preexisting rocks and the subsequent transportation and deposition of the weathering products.

Medium-grained rocks composed mainly of sand are called sandstone, or sometimes arenite if well sorted. Sediment grains in sandstone can having a wide variety of mineral compositions, roundness, and sorting. The finer‐grained clastic sedimentary rocks are called shale, siltstone, and mudstone. Shale is a smooth, thinly layered rock that is made up of fine‐grained silt and clay particles. Shale is considered a fissile rock because it splits very naturally along its layers.
