Is Marble Sedimentary Igneous Or Metamorphic

Igneous rocks comprise about 95 of the total earth s crust.

Is marble sedimentary igneous or metamorphic.

Foliated metamorphic rocks pr essure squeezes or elongates the crysta ls. Each kind of igneous rocks contains different minerals and has different structures. Its composition is equal to that of granite but forms alternating layers of clear and dark minerals. Its basic component is calcium carbonate.

Hence the study of metamorphic rocks provides an understanding of the pressure and temperatures deep within the earth s crust. Limestone is a sedimentary rock and does not turn into igneous rock but can be metamorphosed to form metamorphic rocks such as marble. It is a sedimentary rock. Marble is a metamorphic rock.

Metamorphic rocks are formed by the changes ageing occuring in either sedimentary or igneous rocks. However the process takes thousands to millions of years. 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 under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. Examples of metamorphic rocks.

However the process takes thousands to millions of years. Sand stone is not a metamorphic rock. All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

Marble is a non foliated metamorphic rock. Compact metamorphic rock that evolved from limestone rocks subjected to high temperature and pressure. There are many types of igneous rocks. These are the rocks that form by the effects of heat pressure and shear upon igneous and sedimentary rocks.

The process begins when rocks thrust upwards by tectonic forces and eroded by wind or water. Metamorphic rocks are an important topic in geology. Metamorphic rock can change into igneous or sedimentary rock. The existing rock type which undergoes a change is referred to as the protolith.

Some form during mountain building by forces of others from the heat of igneous intrusions in regional metamorphism others from the heat of igneous intrusions in contact metamorphism.
