Igneous Rocks have many different mineral compositions.
---- * Felsic-High in silica,low density,light colored
* Mafic-less silica than felsic,dark colored,higher density than felsic * Ultramafic-lowest content of silica

∙ 15y agoMany minerals are present in igneous rocks. For example, potassium feldspar and quartz are present in Granite. Also, plagioclase feldspar and small concentrations of amphibole and pyroxene are found in Diorite. Peridotite includes olivine and pyroxene.

∙ 12y agoThere is a vast range of minerals found in igneous rocks, so I would not be so quick to restrict it to just six. Primarily, Quartz, Feldspar (Orthoclase and Plagioclase) and Mica (Muscovite and Biotite) may be found in igneous rocks (these minerals are the common components of Granite), while Olivine and Amphibole are also common. There is no restriction, and other denominations of the groups 'Feldspar' and 'Mica' may also be found, therefore branching out into many more than six types.

What is the difference between metaporphic and igneos rock?
The difference between metaporphic and ignous rock are that ignous rock is formed by cooling of magma and metaporphic is formed by temperature and pressure changes inside the earth
What is the range of specific gravity of most common rock-forming minerals?
Silicates are the most common rock-forming minerals. They tend to have a specific gravity range of 2-4.
What two minerals are basalt volcanic rock in rich in?
Iron and magnesium are the two common minerals in basalt. The rock is poor in silica though.
What is the common mineral that forms the rocks of earth's crust?
There are several common rock forming minerals, but the most common single mineral of the crust is quartz.
What happens to lava when it hits earth's surface?
The magma inside a volcano will ooz out running down the sides. Eventualy the lava will harden into ignous rock.
