Marble 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.Chemically, marble is known as calcareous rock.

Chemical Composition of Marble
Marble is a type of rock that is formed from the metamorphism of limestone or dolomite rock. The chemical composition of marble consists of calcium carbonate (CaCO3) in the form of calcite or dolomite. It also contains other minerals such as quartz, pyrite, and mica.
Calcareous Rock
Calcareous rocks are rocks that are composed of calcium carbonate, either pure or mixed with other minerals. Marble is a type of calcareous rock that is composed of pure calcium carbonate in the form of calcite. Other types of calcareous rocks include limestone, chalk, and travertine.
Metamorphic Rock
Marble is a metamorphic rock that is formed by the metamorphism of limestone or dolomite rock. Metamorphism is the process of changing the texture and mineral composition of a rock due to high pressure and temperature.
Argillaceous Rock
Argillaceous rocks are rocks that are composed of clay minerals such as kaolinite or illite. Marble is not an argillaceous rock because it does not contain any clay minerals.
Silicious Rock
Silicious rocks are rocks that are composed of silica (SiO2) minerals such as quartz or chalcedony. Marble may contain some silica minerals, but it is not considered a silicious rock because its primary mineral composition is calcium carbonate.
Conclusion
In conclusion, marble is a calcareous rock that is composed of pure calcium carbonate in the form of calcite. It is formed by the metamorphism of limestone or dolomite rock, and it does not contain any clay minerals or significant amounts of silica minerals.

As per geological classification it is a metamorphic one....
Limestone under pressure becomes Marble..
as per chemical classification it is calcareous as it is chemically made up of calcium carbonate.
