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. It usually has a whitish color. Composed of calcite and clays. Igneous rock sedimentary rock and metamorphic rock.

Travertine is a sedimentary rock. Breccia pronounced bret cha is usually listed under sedimentary rocks but igneous and metamorphic rocks may become shattered too. It is safest to think of brecciation as a process rather than breccia as a rock type. Detritic sedimentary rock of different colors which contains clasts of sand size.

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. As a sedimentary rock breccia is a variety of conglomerate. Composed of clastic debris in particles the size of clay and silt. The clasts and matrix are typically cemented by calcium carbonate iron oxide.

Igneous rocks are formed when molten substances below the earth surface cools down and solidifies. These molten substances are called magma or lava magma can be derived from melting of existing rocks on the earth crust. The limestone the source material for marble forms when calcium carbonate precipitates out of water or when organic debris shells coral skeletons accumulate. Metamorphism causes variable recrystallization of the original carbonate mineral grains.

Common clastic sedimentary rocks are listed on the table below. They are listed by grain size in decending order. 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. It can be white black or brown.

Marble is a rock resulting from metamorphism of sedimentary carbonate rocks most commonly limestone or dolomite rock. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals. It comes in many colors besides white and black. There are many types of metamorphic 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.
