limestones are organic sedimentary rocks formed from the accumulation and deposition of the hard part(skeletal part) of marine organisms. They are surfacial rocks formed at low temperatures and pressures.

∙ 10y agoLimestone is sometimes reffered to as biological as limstone is a sedimentary rock thats is formed from deposits of the remains of sea organisms such as shellfish and corals. The hard parts of the dead animals contain calcium carbonate. These deposdits are cemented together over a peroed of time very much as sedimentary rocks form wethered rocks. Coal is very like limestone except formed by reamains of dead plants and other millions of year compacted.

How do chemical sediments produce rock?
Chemical sediments, when conditions are right, precipitates to form chemical sediments. This precipitation occurs one of two ways, by physical processes, or by biochemical origin.
Is marble man made?
No, marble is a metamorphic rock that forms naturally from limestones.
What type of sedimentary rock is chalk clastic chemical or biochemical?
Chalk is a biochemical sedimentary rock.
Where is chert found?
Chert is usually found in the form of nodules or lenses in bodies of limestones or dolomites.
Is limestone a silicate mineral?
No. Dolomite is formed by the replacement of Calcium in the mineral calcite by Magnesium, giving the chemical formula (Ca,Mg)CaCO3. Rocks formed largely of calcite are called limestones, and those which show extensive Magnesium substitution in calcite are called Dolomitic limestones.
Biochemical limestones are dominated by carbonate mud fragments of?
calcitic and aragonitic skeletons of marine invertebrates
Do evaporites have a biochemical origin?
Evaporates do not have a biochemical origin. An evaporate is a mineral deposit that is left after a body of water evaporates.
Does most limestone have a biochemical origin?
Yes. Most limestone is biochemical.
Origin other details of lime stone with examples?
Limestones are chemical sedimentary rocks, also called carbonate rock as it is made up of the carbonate radical CO3, hense Calcite CaCO3 Limestone. Although some limestones form by inorganic chemical precipitation most limestones are biochemical because they are mostly composed by organisms. Examples of limestone include Coquina composed almost entirely of fragmented seashells and Chalk, composed largely of microscopic shells.
What terrain is it in the Caribbean islands?
Most are volcanic in origin (some are reef limestones).
Who proposed the biochemical theory of origin of life?
Alexander Ivanovich Oparin was a Soviet biochemist who, in 1924, put forward a coherent theory for the origin of life through gradually increasing sophistication of biochemical change in his book The Origin of Life.
What sedimentary rock is from plant origin?
coal, some limestones are from plant types of diatoms.
What are limestones?
shells
Why is limestones important?
As it can be used for housing materials which would give us many jobs !
What is chichen itza made of?
limestones
What are limestones made from?
Calcium carbonate
Is coal an igneous rock of biochemical origin?
While of biochemical origin, coal is not considered an igneous rock, but rather a sedimentary one, due to its process of formation wherein dead and decaying organic matter (such as animal and plant matter, typing being found in bogs or swamps) was compressed into rock form over a period of several hundred million years.
