Why are mafic minerals dark in color?
Mafic minerals are dark in color because they contain high levels of iron and magnesium, which are elements that produce dark hues. The presence of these elements in the mineral's chemical composition gives it a darker color compared to minerals with lower iron and magnesium content.
What is a mafic rock and what color is it?
A Mafic rock is a type of igneous rock that is rich in Iron and Magnesium instead of silica. The rocks are also darker in color like Basalt.
What is the definition of mafic?
Mafic is a term used to describe an igneous rock that is usually dark in color, with a chemistry that may be high in magnesium and iron, like basalt. Mafic is also a term used to describe a type of magma that is high in calcium, magnesium and iron, and relatively low in silica, compared to felsic magma.
What minerals are found in mafic rocks?
mafic rocks can be made up of orthoclase feldspar and quartz
What is the dark colored igneous rock with rich in iron and magnesium?
The dark-colored igneous rock rich in iron and magnesium is called basalt. Basalt is a fine-grained rock that is commonly found in volcanic areas and oceanic crust. It is characterized by its dark color due to the presence of minerals like pyroxene and olivine.
Which igneous rock has a dark color?
Mafic
What mafic is like?
Mafic is a silicate mineral or rock that is rich in magnesium and iron, and is usually dark in color. It is formed from cooling volcanic lava.
Why are mafic minerals dark in color?
Mafic minerals are dark in color because they contain high levels of iron and magnesium, which are elements that produce dark hues. The presence of these elements in the mineral's chemical composition gives it a darker color compared to minerals with lower iron and magnesium content.

What is the definition of mafic?
Mafic is a term used to describe an igneous rock that is usually dark in color, with a chemistry that may be high in magnesium and iron, like basalt. Mafic is also a term used to describe a type of magma that is high in calcium, magnesium and iron, and relatively low in silica, compared to felsic magma.
What are at least 5 examples of mafic igneous rock?
Basalt, Scoria, Diabase, Basaltic Glass, Gabbro. Obsidian may appear to be mafic due to its dark color but it is actually felsic
What minerals are found in mafic rocks?
mafic rocks can be made up of orthoclase feldspar and quartz
What color is peridotite?
The igneous rock peridotite has a very high color index. It is comprised of more than 95% mafic minerals (like olivine), giving it a dark green color.
Is basalt an example of a felsic rock?
No, basalt is not an example of a felsic rock. Basalt is an example of a mafic rock, which is rich in iron and magnesium and typically dark in color. Felsic rocks, on the other hand, are rich in silica and aluminum and are lighter in color.
Magma that is relatively thin dark colored and low in silica?
This type of magma is called mafic magma. It has a low viscosity due to its low silica content, allowing gases to escape easily. It typically contains high levels of iron and magnesium, making it darker in color.
What is the dark colored igneous rock with rich in iron and magnesium?
The dark-colored igneous rock rich in iron and magnesium is called basalt. Basalt is a fine-grained rock that is commonly found in volcanic areas and oceanic crust. It is characterized by its dark color due to the presence of minerals like pyroxene and olivine.
Why gabro color is black?
The igneous rock gabbro is black because its composition is mafic. Mafic rocks are low in silica and very high in magnesium and iron. It is the magnesium- and iron-rich content that causes its color to be black.
