Calcite Through much of Alabama''s geologic past, the state was covered by ancient oceans, swamps, and other nearshore environments. The sediment left behind in these environments composes most of the state''s bedrock: limestone, sandstone, shale, and chalk. All of these deposits are economically very important to Alabama.
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 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.

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.
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
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.
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
Great deposits of coal, sandstone, shale and limestone are often found together in sequences hundreds of feet thick. The key to large productive coal beds or seams seems to be long periods of time of organic accumulation over a large flat region, followed by a rapid inundation of sand or soil, and with this sequence repeating as often as possible.

coal Coal is a biochemical rock formed by the accumulation of plant material that is later buried and partially altered to a carbonrich rock. Different grades of coal reflect differences in composition and degree of alteration.
Sep 27, 2010· Best Answer: 1. Chemical composition. Limestone is predominantly made up of calcite (calcium carbonate). Coal is chiefly carbon. Both have impurities. 2. Mechanism of formation. Limestone is a chemical precipitate that forms in warm, relatively shallow ocean waters. Coal is .
