Other intrusive igneous rocks include gabbro, diorite, syenite, monzonite, granodiorite, monzodiorite, anorthosite, troctolite, peridotite, and pyroxeneite.
Extrusive igneous rocks include dacite, andesite, phonolite, and trachyte when classified by composition, and tuff, and scoria in terms of texture.
some examples of igneous rocks are granite,basalt,and rhyolite and driolite
== == Rhyolite, basalt, pumice, obsidian, andesite, dacite, tuff, welded tuff, scoria.
Examples of igneous rocks include granite, basalt, and obsidian. The chemical formula for granite is roughly SiO2 (silicon dioxide), for basalt it's typically SiO2, Al2O3, FeO, MgO, CaO, and for obsidian it's SiO2 with minor impurities giving it a glassy texture.
Granite has large mineral grains compared to obsidian, basalt, and pumice. Granite is an intrusive igneous rock that forms deep within the Earth's crust, allowing for the growth of large mineral crystals due to slow cooling. Obsidian, basalt, and pumice are extrusive igneous rocks that cool quickly at the Earth's surface, resulting in smaller mineral grains or a glassy texture.

Basalt and pumice.
Peridotite, andesite, pumice, rhyolite, obsidian, granite, and basalt.
Basalt, Rhyolite, Obsidian and Andesite. There's many more but these are the main ones.
== == Igneous rocks have formed from molten material either above (extrusive) or below (intrusive) ground level. Extrusive igneous rocks include obsidian, basalt, and rhyolite; intrusive igneous rocks include gabbro and granite.

An example of an extrusive igneous rock is basalt. Basalt forms from the rapid cooling of lava on the Earth's surface and is commonly found in volcanic areas. It has a fine-grained texture due to its quick cooling process.
Rocks formed from solidified molten rock are classified as igneous rock. Examples would be basalt, granite, gabbro, pumice, obsidian, and rhyolite.
Examples of igneous rocks include granite, basalt, and obsidian. The chemical formula for granite is roughly SiO2 (silicon dioxide), for basalt it's typically SiO2, Al2O3, FeO, MgO, CaO, and for obsidian it's SiO2 with minor impurities giving it a glassy texture.
Three types of igneous rocks are basalt, granite, and obsidian. Basalt is a dark-colored fine-grained rock, granite is a light-colored coarse-grained rock, and obsidian is a natural glass formed from rapidly cooled lava.
