Marble Igneous Sedimentary Or Metamorphic

Gneiss marble slate schist and quartzite are some of the different types of metamorphic rocks.

Marble igneous sedimentary or metamorphic.

Marble is a coarse grained metamorphic rock that can be many colors including pink white yellow brown green or black. 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. It is a sedimentary rock. The major types of metamorphism are contact and regional.

From the terminology itself igneous means from fire or heat. Marble is a non foliated metamorphic rock. At the surface metamorphic rocks will be exposed to weathering processes and may break down into sediment. In this hand specimen of vermont marble the crystals are small.

This happens due to geologic uplift and the erosion of the rock and soil above them. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Metamorphic rocks are formed by the changes ageing occuring in either sedimentary or igneous rocks. All metamorphic rock is altered partially re melted and generally highly crystalline.

Marble is a common building and ornamental stone. There s lots of options for what a metamorphic rock is made up as well. They can be divided into many categories but they are typically split into. Based on the rock formations there are three basic classes which include igneous sedimentary and metamorphic.

Although metamorphic rocks typically form deep in the planet s crust they are often exposed on the surface of the earth. Foliated metamorphic rocks pressure squeezes or elongates the crystals. Igneous rocks form from the cooling of magma molten materials in the earth s crust. Intense temperatures and pressure beneath the earth cause physical and chemical change to igneous and sedimentary rocks causing them to form metamorphic 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. 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. This type of metamorphic rock consists of recrystallized calcite in limestone or dolomite in dolomite rock.

The original rock type was limestone. Limestone a sedimentary rock will change into the metamorphic rock marble if the right conditions are met. Marble is made by regional metamorphism of limestone or dolomite rock causing their microscopic grains to combine into larger crystals.
