Can the minerals which form an intrusive rock also form the same rock but is an extrusive rock?

Yes. For example gabbro and basalt are chemically equivalent (and so are composed of the same minerals), however gabbro is intrusive and basalt is extrusive.

Are mafic rocks solely intrusive or extrusive?

No. The terms felsic and mafic refers to the relative content of certain minerals in the magma or rock. A mafic rock can be extrusive like basalt, or intrusive like gabbro. Basalt and gabbro can be identical in chemical composition.


What are the most common intrusive and extrusive rocks?

Some common intrusive rocks include granite, diorite, and gabbro, while common extrusive rocks include basalt, andesite, and rhyolite. Intrusive rocks form beneath the Earth's surface from slowly cooling magma, while extrusive rocks form from rapidly cooling lava on the Earth's surface.
