Marble Is An Example Of Sedimentary Rocks

Composed mainly of calcium carbonate.

Marble is an example of sedimentary rocks.

It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite. We have 3 main types or classes of rock based on how they are formed. It comes in many colors besides white and black. Grain size is one factor in classifying sedimentary rocks clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window.

There are many types of metamorphic rocks. It can be white black or brown. Composed of calcite and clays. Metamorphism causes variable recrystallization of the original carbonate mineral grains.

Detritic sedimentary rock of different colors which contains clasts of sand size. Limestone a sedimentary rock changes to form marble. Common clastic sedimentary rocks are listed on the table below. Igneous rock sedimentary rock and metamorphic rock.

Breccia pronounced bret cha is usually listed under sedimentary rocks but igneous and metamorphic rocks may become shattered too. These molten substances are called magma or lava magma can be derived from melting of existing rocks on the earth crust. Travertine is a sedimentary rock. The clasts and matrix are typically cemented by calcium carbonate iron oxide.

Conglomerate k ə n ˈ ɡ l ɒ m ər ɪ t is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel size clasts a conglomerate typically contain a matrix of finer grained sediments such as sand silt or clay which fills the interstices between the clasts. Marble is a rock resulting from metamorphism of sedimentary carbonate rocks most commonly limestone or dolomite rock. As a sedimentary rock breccia is a variety of conglomerate. Lacer getty images in the stone trade and common usage any crystalline carbonate that takes a high polish might be called marble sometimes limestone travertine serpentine a silicate and breccia are called marble.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Igneous rocks are formed when molten substances below the earth surface cools down and solidifies. The limestone the source material for marble forms when calcium carbonate precipitates out of water or when organic debris shells coral skeletons accumulate. It usually has a whitish color.

It is safest to think of brecciation as a process rather than breccia as a rock type.
