What is an example of a magic igneous rock?
I think you mean "mafic", not "magic". Basalt and gabbro are mafic igneous rocks.
What are dark colored rocks called?
If you are referring to igneous rocks, they are classified as mafic.
What are some examples of mafic intrusive igneous rocks?
Gabbro.
What igneous compositions has the lowest silica content mafic ultra mafic intermediate or felsic?
Ultra mafic rocks have the least amount of silica.
How do you classify igneous rocks from other types of rock?
Igneous rocks are identified by first looking at the color index. Felsic igneous rocks contain mostly potassium feldspar. Intermediate igneous rocks contain mostly plagioclase feldspar. Mafic igneous rocks contain pyroxene, olivine, and plagioclase feldspar. Ultra mafic igneous rocks contain mostly olivine. Then igneous rocks are identified based on texture. For example, the texture of igneous rocks can be aphanitic, pegmatitic, phaneritic, glassy, vesicular, etc.
What is the dark colored igneous rock with rich in iron and magnesium?
These rocks are called mafic igneous rocks, such as basalt. == ==

What minerals are present in felsic rocks and mafic rocks?
Felsic refers to igneous rocks that are relatively high in silica and aluminum. Mafic refers to igneous rocks that are higher in magnesium and iron than felsic rocks.
Mafic igneous rocks tend to form?
Dark colored rocks.
What are dark colored rocks called?

What is a Precambrian's shield?
How are mafic and felsic igneous rocks different
What are some examples of mafic intrusive igneous rocks?
Gabbro.
What are the terms felsic and mafic used by geologists to describe?
They are descriptive terms as to the relative silica content of igneous rocks. Igneous rock which is high in silica is referred to as felsic. Igneous rock which is relatively low in silica is referred to as mafic.
What igneous compositions has the lowest silica content mafic ultra mafic intermediate or felsic?
Ultra mafic rocks have the least amount of silica.

Olivine and pyroxene are commonly found in igneous rocks that are?
Mafic, with high density
What rock contains high density minerals such as olivine?
Mafic, igneous rocks
