Limestone is a very common sedimentary rock of biochemical origin. It is composed mostly of the mineral calcite.Sometimes it is almost pure calcite, but most limestones are filled with lots of other minerals and sand and they are called dirty limestones.
Get PriceMarble, on the other hand, is a rock formed when limestone recrystallizes into marble during the mountain-building process. When rocks are formed, limestone is heated and squeezed which causes the grains to recrystallize. It is metamorphic and is usually used as building material and in sculptures.
Get PriceMarble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite.Marble is typically not foliated, although there are exceptions.In geology, the term "marble" refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.
Get PriceJun 05, 2016 · Limestone and marble differ in many ways: Limestone is a rock which is formed when mud, sand and shells are deposited in lakes and oceans developing it into a sedimentary rock. As it is made up of fossilized particles, it is porous and soluble in ...
Get PriceMarble Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the ...
Get PriceLimestone 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.
Get PriceHow do marble form from limestone? ... Limestone is a sedimentary rock and does not turn into igneous rock, but can be metamorphosed to form metamorphic rocks such as marble.

Get PriceCarbonatite is a rare type of igneous rock and marble is a common metamorphic rock. Both are chemically composed of calcium carbonate, but they are not limestones because they are not sedimentary rocks. Other than that, there are no more restrictions. Hence, limestones can be, and indeed are, formed by very different mechanisms.
Get PriceHow do you recognize limestone and marble? The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock.
Get PriceThe Acid Test on Rocks. LIMESTONE, DOLOSTONE, AND MARBLE. Some rocks contain carbonate minerals, and the acid test can be used to help identify them. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Dolostone is a rock composed of almost entirely of dolomite. It will produce a ...
Get PriceMarble: Marble is a metamorphic rock. Metamorphic: This is a process of change, by change what I mean is, change of other sedimentary, igneous or an older metamorphic rock itself. What change happens? During metamorphism the rock (limestone in ...
Get PriceLimestone 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 [[]] 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.
Get PriceLimestone is a naturally occurring sedimentary rock. It consists of calcium carbonate (CaCO3) in its very pure form. Limestone is made by the accumulation of fossils of various marine organisms such as corals, algae, and mollusks and also by depos...
Get PriceThe main difference between the two is that marble is a metamorphic rock, while limestone is a sedimentary rock. Sedimentary rock is formed from minerals and particles – limestone is usually formed under water, which is why it often has shells, sand or mud particles in it.
Get PriceCarbonatite is a rare type of igneous rock and marble is a common metamorphic rock.

Get PriceMarble is a metamorphic rock formed when limestone is subjected to high pressure or heat. In its pure form, marble is a white stone with a crystalline and sugary appearance, consisting of calcium carbonate (CaCO 3).Usually, marble contains other minerals, including quartz, graphite, pyrite, and iron oxides.These minerals can give marble a pink, brown, gray, green, or variegated coloration.
Get PriceMetamorphic Rocks. Mineral information is presented here; Pictures of minerals are found at the bottom of the page. Marble is metamorphosed limestone or dolomite. Both limestone and dolomite have a large concentration of calcium carbonate (CaCO3). Marble has many different sizes of crystals.
Get PriceCompositionally simple sedimentary rocks, such as quartz sandstone and limestone (calcite) do not change composition with metamorphism - their chemistry is too simple. Quartz remains quartz, and calcite remains calcite. The rocks do recrystallize, though, forming granular rocks with fused grains; the rocks quartzite and marble.
Get PriceInteresting Facts about Rocks. The word "igneous" comes from the Latin word "ignis" which means "of fire." Ores are rocks that include minerals that have important elements such as metals like gold and silver. Sedimentary rocks form layers at the bottoms of oceans and lakes.
