Is limestone chemical organic or clastic?
CHEMICAL SEDIMENTARY ROCKS – formed when dissolved substances precipitate from water to form sediments and eventually rock; include salts such as ROCK SALT, GYPSUM, and LIMESTONE, and biochemically mediated rocks such as peat, and reef rock (an organic limestone).
Is limestone chemical and organic?
Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. It can also form by chemical sedimentary processes, such as the precipitation of calcium carbonate from lake or ocean water.
Is limestone organic or inorganic?
Limestones are formed by either organic or inorganic processes, and may be detrital, chemical, oolitic, earthy, crystalline, or recrystallized; many are highly fossiliferous and clearly represent ancient shell banks or coral reefs.
How can limestone be both organic and chemical?
Limestone is a rock that is composed primarily of calcium carbonate. It can form organically from the accumulation of shell, coral, algal, and fecal debris. It can also form chemically from the precipitation of calcium carbonate from lake or ocean water.
Is limestone organic sedimentary rock?
Coquina, bioclastic limestone, and skeletal limestone are also technically organic sedimentary rocks but are usually grouped with the other limestones as being chemically precipitated.
How is limestone formed chemically?
Chemical limestones Some limestones are formed by direct chemical precipitation from marine and other waters saturated with calcium carbonate. If carbon dioxide is removed from this water by warming, agitation or photosynthesis, there is a tendency for calcium carbonate to be precipitated.
What is chemical limestone?
Limestone is a sedimentary rock made of calcium carbonate (CaCO3), usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well. However, minor constituents of clay, iron carbonate, feldspar, pyrite, and quartz is also commonly present.
Why is limestone both organic and chemical?
Organic Sedimentary Rocks Plant bodies are lithified to become coal. When shells are cemented together they make a type of limestone. So limestone can be considered chemical or organic.
What is limestone chemistry?
What is made from limestone?
It is the raw material for the manufacture of quicklime (calcium oxide), slaked lime (calcium hydroxide), cement and mortar. Pulverized limestone is used as a soil conditioner to neutralize acidic soils (agricultural lime). Is crushed for use as aggregate—the solid base for many roads as well as in asphalt concrete.
What is the chemical composition of limestone?
Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris.
Why is limestone considered to be an organic rock?
Because limestone contains the remains of dead organisms, it is considered an organic sedimentary rock. There are rare chemical sedimentary rocks that form from the precipitation of calcium carbonate from ocean water. Lithographic limestone is a type of limestone that contains fossils.
What kind of rock is porous limestone made of?
Coquina – A sedimentary rock that is composed mostly of fragments of shells Tufa – Porous limestone rock formed when carbonate minerals precipitate out of ambient temperature water Two major classification schemes, the Folk and the Dunham, are used for identifying limestone and carbonate rocks.
Is the Coquina in skeletal limestone organic or chemical?
Coquina, bioclastic limestone, and skeletal limestone are also technically organic sedimentary rocks but are usually grouped with the other limestones as being chemically precipitated. Thereof, is Coquina organic clastic or chemical?
Where does the limestone in the ocean come from?
It may be precipitated from water ( non-clastic, chemical or inorganic limestone), secreted by using marine organisms including algae and coral (biochemical limestone), or can shape from the shells of lifeless sea creatures (bioclastic limestone).
