Is Marble Extrusive Or Intrusive

By contrast intrusive rocks are formed from magma that was forced into older rocks at depth within earth s crust.

Is marble extrusive or intrusive.

Carbonatite k ɑːr ˈ b ɒ n ə t aɪ t is a type of intrusive or extrusive igneous rock defined by mineralogic composition consisting of greater than 50 carbonate minerals. The terms intrusive and extrusive apply to igneous rocks. Igneous rocks from the latin word for fire form when hot molten rock crystallizes and solidifies. Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form.

Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. The molten material then slowly solidifies below earth s surface where it may later be exposed through erosion. The question is granite intrusive or extrusive is therefore a common among many people. Carbonatites may be confused with marble and may require geochemical verification.

Igneous rocks are divided into two groups intrusive or extrusive depending upon where the molten rock solidifies. 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. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite.

Extrusive rock any rock derived from magma molten silicate material that was poured out or ejected at earth s surface.
