Marble Igneous Sedimentary Or Metamorphic

Marble is a non foliated metamorphic rock.

Marble igneous sedimentary or metamorphic. From the terminology itself igneous means from fire or heat. Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Based on the rock formations there are three basic classes which include igneous sedimentary and metamorphic. 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.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Marble is a common building and ornamental stone. In this hand specimen of vermont marble the crystals are small. There s lots of options for what a metamorphic rock is made up as well.

Sand stone is not a metamorphic rock. The former takes place when magma is injected into the surrounding solid rocks whereas the latter is primarily associated with large masses of rock spread over a very wide area. Intense temperatures and pressure beneath the earth cause physical and chemical change to igneous and sedimentary rocks causing them to form metamorphic rocks. Igneous rocks form from the cooling of magma molten materials in the earth s crust.

Because the parent rock limestone is composed of calcite marble with also react to and dissolve in acids. From there it could be igneous it could be sedimentary or it could be metamorphic if it s older and has undergone an extreme amount of heat and compression. Marble is a metamorphic rock. All metamorphic rock is altered partially re melted and generally highly crystalline.

The major types of metamorphism are contact and regional. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals. Marble is a coarse grained metamorphic rock that can be many colors including pink white yellow brown green or black.

At the surface metamorphic rocks will be exposed to weathering processes and may break down into sediment. It is a sedimentary rock. Foliated metamorphic rocks pressure squeezes or elongates the crystals. They can be divided into many categories but they are typically split into.

Gneiss marble slate schist and quartzite are some of the different types of metamorphic rocks. The original rock type was limestone. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met.
