Is marble extrusive or intrusive.

The terms intrusive and extrusive apply to igneous rocks. Carbonatites may be confused with marble and may require geochemical verification. Some cool so. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite.

The molten material then slowly solidifies below earth s surface where it may later be exposed through erosion. By contrast intrusive rocks are formed from magma that was forced into older rocks at depth within earth s crust. The terms magma and lava have been used interchangeably for a long time and rightfully so. Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form.

The question is granite intrusive or extrusive is therefore a common among many people. The melt originates deep within the earth near active plate boundaries or hot spots then rises toward the surface. The coarse grained rock is made up of different elements including quartz and feldspar and its formation makes it an intrusive rock. Igneous rocks are divided into two groups intrusive or extrusive depending upon where the molten rock solidifies.

Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals.
