The table below includes specific environments where various types of sediments are deposited and common rocks, structures, and fossils that aid in deducing the depositional environment from examining a sedimentary rock outcrop. Although this is not a complete list, it is a good introduction to depositional environments. Continental; Transitional

Organic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris. Photos and brief descriptions of some common sedimentary rock types are shown on this page.

Limestone, found throughout Tennessee, was designated the official state rock in 1979. Tennessee also recognized an official state stone; agate (later renamed the "state mineral"). All State Rocks & Minerals. Tennessee Marble. Tennessee marble (the metamorphic version of limestone) is widely used in public and private buildings.
Coal. Coal is a chemical sedimentary rock made mostly of carbon. It forms from the remains of plants that lived in moist environments rich in trees, shrubs, water, and mud. In such swampy settings, the dead plant debris is quickly buried and thus escapes rotting away at the earth's surface.
Some Facts on Coal. Whether you realize it or not, coal is a big part of your daily life. In the past, coal has been used to heat homes, to cook with, and even to draw with.
Feb 25, 2007· Best Answer: The other answer is excellent and informative, but doesn't really address how these materials are formed. Oil is formed from buried organic material. In most examples oil forms from the remains of phytoplankton (microscopic plants) and zooplankton (microscopic animals) which sink to the ocean floor and are buried by mud, clay, and silt, which later forms shale.
Limestone is a sedimentary rock that contains at least 50% calcium carbonate (CaCO3). Because sedimentary rocks are made of various types of sediments, the other 50% of a limestone rock could be virtually any other mineral. Limestone originates in wet areas which mean it could also be composed of shells and waste matter from organisms.
In a flare kiln, a bottom layer of coal was built up and the kiln above filled solely with chalk. The fire was alight for several days, and then the entire kiln was emptied of the lime. In a draw kiln, usually a stone structure, the chalk or limestone was layered with wood, coal or coke and lit.
Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
The pictures below show that quarry, and beach rip rap, which is one use of the limestone. Most of the limestone is transported from this quarry by truck, but some is still moved by rail. In addition to limestone, Michigan also produces pure lime as well. Lime is purified limestone, and is often of more value to industry than is limestone.

Coal mining operations enjoyed high demand and constant work during World War I and World War II. The introduction of improved mechanization made surface mining a more profitable undertaking than underground mining. By the 1950s, coal markets were in severe decline, however, and most of Alabama's mines closed.
- chemical limestone (calcium carbonate) that is formed on the outside of hot springs because when the water touches the ground it cools and CO2 leaves as gas which means that the solution can dissolve calcite LESS --> calcite precipitates into limestone
The Sharon Coal and Limestone Company has but one mine in this county, the others being in Lawrence and Butler, all being situated on the Wolf Creek branch of the Pennsylvania from Leesburg. The general superintendent is F.P. Filer, of Mercer, a son of Enoch Filer, one of the foremost developers and managers of coal properties in the last century.
Bituminous coal was first commercially mined in Pennsylvania at "Coal Hill" (Mount Washington), just across the Monongahela River from the city of Pittsburgh. The coal was extracted from drift mines in the Pittsburgh coal seam, which outcrops along the hillside, and .
