Is Marble Igneous Metamorphic Or Sedimentary

There are many types of igneous rocks.

Is marble igneous metamorphic or sedimentary.

To aid in their study of the earth geologists group rocks into three categories based on their origin. However the process takes thousands to millions of years. Igneous rocks comprise about 95 of the total earth s crust. Foliated metamorphic rocks pr essure squeezes or elongates the crysta ls.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Slate metamorphic if put under more. Each category is then further subdivided. Metamorphic rocks are formed by the changes ageing occuring in either sedimentary or igneous rocks.

They can be divided into many categories but they are typically split into. Shale sedimentary could have become slate. All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks. Then due to various conditions within the earth the existing rock was changed into a.

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. Sand stone is not a metamorphic rock. Igneous rocks formed when liquid magma or lava magma that has emerged onto the surface of the earth cooled and hardened.

Metamorphic rock can change into igneous or sedimentary rock. Marble is a non foliated metamorphic rock. It is a sedimentary rock. The original rock is subjected to heat temperatures greater than 150 to 200 c and pressure 100 megapascals 1 000 bar or more causing profound physical or chemical change the protolith may be a sedimentary igneous or existing metamorphic rock.

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. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. Marble is a metamorphic rock. A metamorphic rock on the other hand began as a rock either a sedimentary igneous or even a different sort of metamorphic rock.

However the process takes thousands to millions of years. Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks. Each kind of igneous rocks contains different minerals and has different structures. A gneiss could have come from a granite igneous.

Igneous sedimentary and metamorphic. You may want to have several sample s of metamorphic rocks and the rocks they changed from.
