Marble Is An Example Of Sedimentary Rocks

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.

Marble is an example of sedimentary rocks.

Common clastic sedimentary rocks are listed on the table below. Igneous rocks are formed when molten substances below the earth surface cools down and solidifies. Limestone a sedimentary rock changes to form marble. As a sedimentary rock breccia is a variety of conglomerate.

Composed mainly of calcium carbonate. Travertine is a sedimentary rock. 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.

The clasts and matrix are typically cemented by calcium carbonate iron oxide. There are many types of metamorphic rocks. Composed of calcite and clays. The limestone the source material for marble forms when calcium carbonate precipitates out of water or when organic debris shells coral skeletons accumulate.

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. Composed of clastic debris in particles the size of clay and silt. Detritic sedimentary rock of different colors which contains clasts of sand size. It comes in many colors besides white and black.

They are listed by grain size in decending order. Metamorphism causes variable recrystallization of the original carbonate mineral grains. It can be white black or brown. We have 3 main types or classes of rock based on how they are formed.

It usually has a whitish color. Breccia pronounced bret cha is usually listed under sedimentary rocks but igneous and metamorphic rocks may become shattered too. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals. Marble is a rock resulting from metamorphism of sedimentary carbonate rocks most commonly limestone or dolomite rock.

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