Dark colored igneous rock rich in iron and magnesium?
Dark, mafic rock is relatively rich in iron and magnesium.
Igneous rocks that are dense and dark colored they form from magma that is rich in iron and magnesium and poor in silica?
These types of igneous rocks are commonly known as mafic rocks. They have a high density due to the presence of minerals like olivine, pyroxene, and amphibole, which are rich in iron and magnesium. Examples include basalt and gabbro.
What property is common to most dark-colored igneous rocks?
Most dark-colored igneous rocks are mafic, which means they are rich in minerals like pyroxene, olivine, and amphibole. These minerals give the rocks their dark color due to higher iron and magnesium content. Additionally, dark-colored igneous rocks are typically extrusive, forming from rapid cooling at the Earth's surface.
What property is common to most dark colored igneous rocks?
Most dark-colored igneous rocks have a high density.
Are basaltic igneous rocks high in iron and magnesium?
Yes, basaltic igneous rocks are typically high in iron and magnesium. This is because basalt forms from the partial melting of the Earth's mantle, which is rich in these elements. The high iron and magnesium content gives basalt its dark color and dense, fine-grained texture.
Are dark-colored igneous rocks rich in iron and magnesium?
Dark, mafic rock is relatively rich in iron and magnesium.
Dark colored igneous rock rich in iron and magnesium?
Dark, mafic rock is relatively rich in iron and magnesium.
What are dark colored often extrusive igneous rocks containing iron magnesium or calcium?
They are referred to as mafic, a word representing their magnesium and iron content.
What is the igneous rock that is dense and dark colored and forms from magma that is rich in iron and magnesium but poor in silica That has 8 letters?
The igneous rock you are referring to is basalt. It is a fine-grained, dense, and dark-colored rock that forms from low-silica magma rich in iron and magnesium.
In general how does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt. Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.
Is basalt a dark and green igneous rock?
Basalt is a dark-colored igneous rock that ranges from black to dark green in color. It is commonly found in volcanic areas and is rich in iron and magnesium minerals.
Igneous rocks that are dense and dark colored they form from magma that is rich in iron and magnesium and poor in silica?

What are dark colored rocks called?
If you are referring to igneous rocks, they are classified as mafic.
What property is common to most dark colored igneous rocks?
Most dark-colored igneous rocks have a high density.
How does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.
Are basaltic igneous rocks high in iron and magnesium?
Yes, basaltic igneous rocks are typically high in iron and magnesium. This is because basalt forms from the partial melting of the Earth's mantle, which is rich in these elements. The high iron and magnesium content gives basalt its dark color and dense, fine-grained texture.
