Igneous rocks are classified depending on whether they form inside the earths crust, or outside as intrusive and extrusive respectively. 10 examples of igneous rocks 1. Plutonic rocks 2. Volcanic rocks 3. Basalt 4. Obsidian 5. Granite 6. Basalt 7. Diorite 8. Grabo 9. Breccia 10. Andesite
Igneous Rock Example. Pumice and Obsidian are the categories of extrusive igneous rocks. We use Pumice in making a lightweight concrete and Obsidian is used in ornaments. Granite and Diorite are intrusive igneous rocks. Both of these are used as building materials.
Examples of igneous rocks . Granite plutonic gray or light red. Composed of quartz, potassium feldspar and mica. Porphyry plutonic dark red. Composed of feldspar and quartz. Gabbro plutonic thick texture. It consists of calcium plagioclase, pyroxene, olivine, hornblende and Hypersthene. Sienite plutonic it is distinguished from granite because it does not contain quartz.
Mar 19, 2021 Andesite is an example of an extrusive igneous rock. This rock was formed from the cooling of lava on the surface of the earth. Andesite is a fine grained rock that contains silica and in lower quantities alkali metals such as lithium, sodium, and potassium.
Nov 15, 2018 Igneous Rock Examples. Several factors determine the type of igneous rock that is going to be created. These factors are intrusive vs. extrusive environments, silica content, temperature during crystallization and mineral content. Listed below are a wide variety of igneous rocks, each with the factors necessary for that igneous rock to be created.
Igneous rock, any of various crystalline or glassy rocks formed by the cooling and solidification of magma, which is a hot 600 to 1,300 C, or 1,100 to 2,400 F molten or partially molten rock. Igneous rocks constitute one of the three principal classes of rocks,
Intrusive igneous rocks cool from magma slowly and have crystals that are easily seen with the naked eye. Examples of intrusive igneous rocks are granite, diorite, gabbro, and peridotite ...
Igneous rock examples. STUDY. PLAY. Fine grained example of mafic igneous rock. Basalt. Course grained example of mafic igneous rock. Gabbro. What color are mafic igneous rocks and how much feMg. Dark, mostly feMg.
One example of extrusive igneous rock an igneous rock that cools above the surface of the ground rather than beneath is obsidian. Obsidian is smooth like glass and usually jet black, although it can be seen in a variety of colors. While it is rather fragile, obsidian breaks with a conchoidal fracture and has very sharp edges.
Granite is one of the most common rocks on Earth, and is the most common igneous rock. This dense stone is used in construction, for everything from basic building to beautiful polished countertops. Because the minerals in the granite crystalized as it cooled, granite often
Extrusive igneous rocks are formed when molten magma spill over to the surface as a result of a volcanic eruption. The magma on the surface lava cools faster on the surface to form igneous rocks that are fine-grained. Examples of such kind of rocks include pumice, basalt, or obsidian. Examples of Igneous Rocks
Igneous rocks are classified according to their mineral content Ultramafic rocks are dominated by olivine andor pyroxene. Mafic rocks are dominated by plagioclase and pyroxene even if you cant see them with the naked eye and smaller amounts of olivine. Intermediate rocks are roughly even mixtures of felsic minerals mainly plagioclase and mafic minerals mainly hornblende, pyroxene ...
Igneous rocks from the Latin word for fire form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.
Sep 11, 2019 Felsic Derived from the words feldspar and silica to describe an igneous rock having abundant light-colored minerals such as quartz, feldspars, or muscovite.. Mafic Derived from the words magnesium and ferric Fe is the chemical symbol for iron to describe an igneous rock having abundant dark-colored, magnesium- or iron-rich minerals such as biotite, pyroxene, or olivine.
Igneous Rock 1. Granite Granite and other rocks of the granite family are the most widely distributed of the deeper plutonic igneous rocks forming the major component of the earths crust. It is a light coloured rock. The dominant mineral of the rock is alkali feldspar which occurs as large crystals.
Igneous rocks are called intrusive or plutonic when they cool and solidify beneath the surface.Because they form within the Earth, cooling occurs slowly.Such slow cooling allows time for large crystals to form, therefore, intrusive or plutonic igneous rocks have relatively large mineral crystals that are easy to see. Granite is the most common intrusive igneous rock Figure 4.4.
Vesicular volcanic rocks Vesicular is the adjective used to modify the name of any fine-grained igneous volcanic rock which has vesicles holes from gas bubbles, making a cinder-like or clinker-like appearance. Example Vesicular basalt.
The following are some examples of commonly found igneous rocks and their uses. Basalt. Most of the basaltic rocks are volcanic or extrusive, while intrusive basalt is formed very rarely. There are also evidences for presence of basaltic rock in the moon and mars. This igneous rock type is identified by its dark shade and fine-grained texture.

The original rock protolith is subjected to heat temperatures greater than 150 to 200 C and pressure 1500 bars, causing profound physical andor chemical change. The protolith may be a sedimentary rock, an igneous rock or another older metamorphic rock.
Diorite, granite, pegmatite are examples of intrusive igneous rocks. Extrusive igneous rock These rocks erupt onto the surface resulting in small crystals as the cooling takes place quickly. The cooling rate is for a few rocks is so quick that they form an amorphous glass. Basalt, tuff, pumice are examples of extrusive igneous rock. Igneous ...
Examples of intrusive igneous rocks include granite, gabbro, diorite and dunite. Extrusive Igneous Rock. Extrusive igneous rocks form when magma reaches the Earths surface a volcano and cools quickly. Most extrusive volcanic rocks have small crystals. Examples of extrusive igneous rocks include basalt, rhyolite, andesite, and obsidian.
Jun 13, 2020 The moon that rotates the earth is also made of igneous rocks. Pumice stone that is used for various purposes is perhaps the example of the lightest igneous rock on planet earth. These rocks are rich in certain types of minerals that help in plants to grow properly. Let us look at some examples of igneous rocks.
The following is an example of igneous rocks. It is not an all inclusive list but a brief pictorial list of some common igneous rocks. Igneous rocks get their name from the latin word for fire igneus. The name is appropriate because these rocks are born of fire. Beneath the thin rocky crust of the earth is
