Sedimentary rocks are usually divided into: siliciclastic rocks and carbonate rocks. Siliciclastics are usually composed of the weathering products of older rocks carried and delivered to a basin of deposition by rivers. Carbonate rock, however, are generally composed of carbonate minerals (e.g. Calcite, Dolomite, Anhydrite..) these minerals form either biologically (as skeletons of sea organisms such as foraminifera, rudists and corals) or chemically by sea water. The most famous carbonate rock is probably Limestone, other rocks include: Dolostone (aka Dolomite) and evaporites; interesting to note that Marble is metamorphosed limestone.

Limestone and dolomite are common rocks that contain carbonate minerals. These rocks form primarily from the accumulation of calcite or aragonite for limestone, and dolomite for dolomite, often from the remains of marine organisms.

What is the chemical formula of marl rocks?
The chemical formula of marl rocks is CaCO3 (calcium carbonate). Marl is a type of sedimentary rock composed of varying proportions of clay and calcium carbonate.
How is carbon dioxide released into the air by carbonate rocks?
Carbonate rocks, like limestone, can release carbon dioxide when they break down or weather. This process, known as chemical weathering, occurs when carbonic acid in water reacts with the minerals in the rocks, leading to the release of carbon dioxide into the air.
What is carbonate weathering?
Carbonate weathering is the process by which rocks containing carbonate minerals (such as calcite) are broken down and dissolved due to exposure to carbon dioxide and water. This process can alter the rocks' chemical composition and form new minerals. Carbonate weathering plays a significant role in the carbon cycle and can affect the acidity of soil and water.
How is carbon dioxide released from carbonate rocks into the atmosphere?
Carbon dioxide is released from carbonate rocks into the atmosphere through processes such as weathering, dissolution, and metamorphism. When carbonate rocks are exposed to water or acidic conditions, they break down and release carbon dioxide as a byproduct. This released carbon dioxide can then be released into the atmosphere through various pathways.
How are most carbonate rocks formed?
Most carbonate rocks, such as limestone and dolomite, are formed through the accumulation and cementation of calcareous marine organisms like corals, mollusks, and algae. These organisms produce calcium carbonate shells and skeletons that build up over time to create carbonate rock formations. Other processes, like precipitation from seawater or chemical reactions in caves, can also contribute to the formation of carbonate rocks.
How did CO2 get locked in carbonate rocks?
Carbon dioxide can get locked in carbonate rocks through processes such as weathering of rocks containing carbonates, which leads to the formation of bicarbonate ions that eventually get precipitated as carbonate minerals (e.g., calcite) in rocks. Over time, this process sequesters CO2 in the form of carbonate minerals in the rocks.
What is the effects of carbonate racks to global climate?
There are two effects of carbonate rocks to the global climate. The two effects of carbonate rocks to the global climate are dissolution and deposition.

carbonate containing rocks
What makes marble result?
Carbonate rocks.
What rocks are a natural source of calcium carbonate?
Limestone, chalk, and marble are examples of rocks that are natural sources of calcium carbonate. These rocks are formed from the accumulation of calcium carbonate minerals over time, which can be used for various purposes including in construction, agriculture, and industry.
Calcium carbonate is a major component of which sedimentary rocks?
Calcium carbonate is a major component of sedimentary rocks such as limestone, chalk, and marble. These rocks form from the accumulation of marine organisms' shells, coral reefs, and precipitated calcite minerals.

How does carbonate get into rocks?
Carbonate minerals can form in rocks through the deposition of calcium carbonate (CaCO3) from marine organisms like shells and coral. It can also be introduced through chemical processes, where carbon dioxide combines with minerals in the presence of water to form carbonates.
