It covers the mineralogy, chemistry, textures, and sedimentary structures that characterise sedimentary rocks, and relates these features to the depositional origin of the rocks and their subsequent alteration by diagenetic processes during burial.
This encyclopedia, which constitutes a wide ranging and authoritative collection of academic articles, covers the sedimentological aspects of sediments and sedimentary rocks. As such the encyclopedia provides a comprehensive, onevolume reference work for students and faculty in universities, and for professionals in geology and allied ...
Sedimentary rocks such as limestone or shale are hardened sediment with sandy or claylike layers (strata). They are usually brown to gray in color and may have fossils and water or wind marks. They are usually brown to gray in color and may have fossils and water or wind marks.
of the Appalachian Plateau are sedimentary rocks of similar age and type to those found in the Valley and Ridge province to the southeast. The fossils they contain belong to the Paleozoic era and were deposited in shallow seas between the Cambrian and Pennsylvanian periods (540300 million years ago).

This is an important point that must be repeated. The oldest sedimentary rocks across the central United States are, for the most part, less than 542 million years old. The crystalline rock that directly underlies these sedimentary layers is more than 1 billion years old.
Chemical sedimentary rocks form when minerals in solution become supersaturated and precipitate. In marine environments, this is a method for the formation of limestone. Another common environment in which chemical sedimentary rocks form is a body of water that is evaporating.

Dolomite rock is a very common sedimentary rock, especially older carbonate rocks (formed before the Mesozoic) tend to be dolomites whereas younger carbonates are predominantly various limestones. Dolomite is usually very similar to limestone and the two are often indistinguishable in the field.
Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral or organic particles ( detritus) to settle in particles that form a sedimentary rock by accumulating are called sediment.
Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semisolid the center of the Earth is a hot, dense metal core.
Sedimentary Rock forms from particles, called sediment, that are worn off other rocks. The particles are sand, silt, and clay. The particles are sand, silt, and clay. Sand has .
VEINS, in geology, masses of rock which occupy fissures in other rocks. They may have originated in many different ways and present a great variety of forms and structures. We may classify them in three groups: (i.) veins of igneous rock, (ii.) of sedimentary, and (iii.) of .

sedimentary rocks (sandstone, shale, and limestone and dolomite) to physical properties (such as velocity, modulus, and porosity). These equations can be used to estimate rock strength from parameters measurable with geophysical well logs.
Metamorphic rock is produced deep beneath the Earth's surface when a preexisting rock type, called the protolith, is transformed under conditions of high temperatures and pressures. The protolith may be sedimentary rock, igneous rock, or older metamorphic rock, and the transformation may involve physical changes, chemical changes, or both.
