These rocks are called mafic igneous rocks, such as basalt. == ==
Dark, mafic rock is relatively rich in iron and magnesium.
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.
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.
Most dark-colored igneous rocks have a high density.
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.

Dark, mafic rock is relatively rich in iron and magnesium.
They are referred to as mafic, a word representing their magnesium and iron content.
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.
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.
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.

If you are referring to igneous rocks, they are classified as mafic.
Most dark-colored igneous rocks have a high density.
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.
