Intrusive igneous rocks come from magma, forming deep underground and taking longer to cool, meaning they form larger crystals. The chemical composition of diorite is intermediate between gabbro and granite. ... Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and/or pyroxene. Compare and contrast extrusive igneous rocks from intrusive igneous rocks in process of formation, cooling time, crystal size and example. Get to know the difference between the two Igneous Rocks by comparing their properties, features, texture, uses and appearance. We have moved all content for this concept to for better organization. However, extrusive rocks form from lava at the surface of the Earth, whereas intrusive rocks form from magma underground, often relatively deep in the Earth. Relevance.
