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. Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form. The terms magma and lava have been used interchangeably for a long time and rightfully so.

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. By contrast intrusive rocks are formed from magma that was forced into older rocks at depth within earth s crust. The molten material then slowly solidifies below earth s surface where it may later be exposed through erosion.

The coarse grained rock is made up of different elements including quartz and feldspar and its formation makes it an intrusive rock. Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. 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.

Igneous rocks from the latin word for fire form when hot molten rock crystallizes and solidifies.
