What type of magma is dark in color?

Why are mafic minerals dark in color?
No. Felsic rocks are light-colored and high in silica. Mafic rocks are generally dark-colored and low in silica.
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.
How can mineral composition affect the color of an igneous rock?
Silicate minerals can be light or dark, but Mafic minerals are dark, which is why Basalt appears dark, while Granite is light because Quartz is also light (in colour, not density).
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?

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 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
Magma that is relatively thin dark colored and low in silica?
A low silica magma is called a "mafic" magma.
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.
How can mineral composition affect the color of an igneous rock?
Silicate minerals can be light or dark, but Mafic minerals are dark, which is why Basalt appears dark, while Granite is light because Quartz is also light (in colour, not density).
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 is the compositions of the ocean floor?
The ocean floor is composed of basaltic rocks. Very mafic (dark) in color. It is thinner yet heavier than continental rock.
