Is marble igneous sedimentary or metamorphic.

Igneous rocks sedimentary rocks and metamorphic rocks are the major three rock types in the earth s crust geologist made this classification based on the geological process that formed these rocks. Metamorphic rocks on the other hand are transformed rocks as a result of exposure to extreme heat and pressure beneath the earth s mantle. 3 igneous rocks can be an important source of minerals and sedimentary rocks or their bedding structure is mostly used in civil engineering. Igneous rocks comprise about 95 of the total earth s crust.

It is a sedimentary rock. A metamorphic rock on the other hand began as a rock either a sedimentary igneous or even a different sort of metamorphic rock. These are the rocks that form by the effects of heat pressure and shear upon igneous and sedimentary rocks. Marble is a metamorphic rock.

Hence the study of metamorphic rocks provides an understanding of the pressure and temperatures deep within the earth s crust. Geologists study the geological properties of metamorphic rocks as their crystalline nature provides valuable information about the. For the construction of housing roads tunnels canals etc. Sedimentary rocks are generally formed by matter that has settled beneath lakes and ocean floors.

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. Then due to various conditions within the earth the existing rock was changed into a. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. They can be divided into many categories but they are typically split into.

Metamorphic rocks are an important topic in geology. Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks. All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks. There are many types of igneous rocks.

Marble is a non foliated metamorphic rock. Igneous rocks formed when liquid magma or lava magma that has emerged onto the surface of the earth cooled and hardened. Sand stone is not a metamorphic rock. Igneous rocks are molten rocks expelled as lava that has cooled and become solid.

Each kind of igneous rocks contains different minerals and has different structures. Metamorphic rocks are formed by the changes ageing occuring in either sedimentary or igneous rocks.
