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

Is granite an intrusive or extrusive rock.

Granite is a coarse grained light colored intrusive igneous rock that contains mainly quartz feldspar and mica minerals. Some cool so. The central cores of major mountain ranges consist of intrusive igneous rocks usually granite. Is granite an intrusive or extrusive rock.

Before discussing further differences between both rocks let us see what is a rock and what are intrusive rocks and extrusive rocks. Derived from the words feldspar and silica to describe an igneous rock having abundant light colored minerals such as quartz feldspars or muscovite. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. Granite has a lot of different colors ranging from white to pink.

The molten material then slowly solidifies below earth s surface where it may later be exposed through erosion. The foidolite rock is a special case in the rock family. The other is extrusive rock that is a volcanic eruption or similar event. Granite the equivalent of its extrusive volcanic rock type rhyolite is a very common type of intrusive igneous rock.

By contrast intrusive rocks are formed from magma that was forced into older rocks at depth within earth s crust. For instance if an extrusive rock comes out as glass with large bubbles it s called scoria. Key terms felsic. It is a rare coarse grained intrusive igneous rock.

Granite is an intrusive rock while rhyolite is an extrusive rock intrusive rocks are rocks that are formed below the earth s surface extrusive rocks are rocks that are formed on the earth s. Intrusive vs extrusive rocks the key difference between intrusive and extrusive rocks is that the intrusive rocks are formed from magma whereas the extrusive rocks are formed from lava. Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form. Rocks that display large granular crystal structure are called pegmatitic.

Pegmatite is an intrusive igneous rock made up of large interlocking crystals the word pegmatite comes from the greek word pegnymi which means to bind together referring to the entwined feldspar and quartz crystals commonly found in the rock. See sierra nevada batholith. It is the intrusive equivalent to the extrusive foidite. Intrusive rock forms within earth s crust from the crystallization of magma.

If the bubbles are minimal the rock is called obsidian. Igneous rocks are classified into two groups depending upon where the molten rock solidifies. Many mountain ranges such as the sierra nevada in california are formed mostly from large granite or related rock intrusions. Intrusions are one of the two ways igneous rock can form.
