what is the difference between chemical and organic sedimentary rocks?

Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution. Organic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris.

Chemical and biogenic sedimentary rocks – Composed of minerals precipitated from water by biologic or inorganic processes or the remains of organisms. The most important property in classifying clastic sedimentary rocks is grain size.

Non-clastic sedimentary rocks are evaporites (like salt and gypsum) or precipitates like calcium carbonate (some types of limestone, and travertine).

The key difference between inorganic and organic carbon is that the inorganic carbon is the carbon extracted from ores and minerals whereas the organic carbon is found in nature from plants and living things.

Sedimentary rocks are formed when small pieces of material are compressed and cemented together over time to form one whole rock. Detrital sedimentary rocks are formed from rock fragments, while chemical sedimentary rocks are formed from mineral crystals that form after dissolving out of water.

Chemical and Biochemical Sedimentary Rocks Chemical sedimentary rock is formed when minerals, dissolved in water, begin to precipitate out of solution and deposit at the base of the water body. ... Due to the manner in which they are formed, these types of rocks exhibit a crystalline texture.

1 Answer. The three basic types of biochemical (biogenic) sedimentary rocks are classified according to their original material: limestone (calcium carbonate), coal (carbon), and chert (silica).

The Difference Between Rocks and Minerals. A mineral is a solid formation that occurs naturally in the earth while a rock is a solid combination of more than one mineral formations which is also occurring naturally. ... A rock can also contain organic remains and mineraloids apart from regular mineral formations.

A mineral is a chemical substance made up of one or more chemicals having a definite crystal structure. Rocks do not have a definite chemical composition whereas minerals do. Sometimes a rock may contain organic remains in it. A mineral, on the other hand, will never have any organic material present within it.

The main difference between the two classes of substances is that organic compounds always contain the element carbon, while most inorganic compounds lack this element. ... With very few exceptions, organic compounds contain carbon atoms bonded to hydrogen atoms to form the C-H bonds.

Similarities: they are both formed from organic remains and both form under enormous pressures in a sedimentary sequence. Differences: coal is formed from land-based plants in bogs and coastal swamps, while oil and gas are derived from tiny marine organisms, such as algae and phytoplankton.

Biochemical sedimentary rocks are formed from organic processes that involve living organisms producing the sediments. These living organisms can be snails and clams whose discarded calcium carbonate shells can form limestone.

Detrital sedimentary rocks are classified according to clast size whereas chemical sedimentary rocks are classified based on their dominant minerals. ... Chalk is a soft, porous rock composed of the hard parts of microscopic marine organisms.

Chemical Sedimentary Rocks. Chemical sedimentary rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water. For example: Take a glass of water and pour some salt (halite) into it.

Basically, these differences center around the fact that coal is found at its site of deposition as a solid and relatively pure massive organic substance, whereas petroleum is liquid and migrates readily from its place of origin into porous reservoir rocks.

Detrital sedimentary rocks are mainly classified by the size of their grain. The largest grain is a boulder, followed by a cobble, a pebble, sand, silt and finally the finest grain, which is clay. ... Chemical sedimentary rocks are composed of mineral crystals that form out of solution.
