Is Marble Sedimentary Igneous Or Metamorphic

Limestone is a sedimentary rock and does not turn into igneous rock but can be metamorphosed to form metamorphic rocks such as marble.

Is marble sedimentary igneous or metamorphic.

Metamorphic rock can change into igneous or sedimentary rock. Igneous rocks comprise about 95 of the total earth s crust. All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks. Metamorphic rocks are an important topic in geology.

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. Examples of metamorphic rocks. It is a sedimentary rock.

However the process takes thousands to millions of years. Compact metamorphic rock that evolved from limestone rocks subjected to high temperature and pressure. These are the rocks that form by the effects of heat pressure and shear upon igneous and sedimentary rocks. Sand stone is not a metamorphic rock.

Its composition is equal to that of granite but forms alternating layers of clear and dark minerals. Each kind of igneous rocks contains different minerals and has different structures. The process begins when rocks thrust upwards by tectonic forces and eroded by wind or water. 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. They can be divided into many categories but they are typically split into. Its basic component is calcium carbonate. Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks.

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. Composed of quartz feldspar and mica. Foliated metamorphic rocks pr essure squeezes or elongates the crysta ls. The existing rock type which undergoes a change is referred to as the protolith.

Hence the study of metamorphic rocks provides an understanding of the pressure and temperatures deep within the earth s crust.
