Why are dark colored igneous rocks heavier than light colored ones?

As a first approximation, the colour of igneous rocks gives an estimate of the concentration of iron in it. Very dark igneous rocks commonly a large fraction of minerals with iron as a major constituent.
As those minerals are denser than most other silicate minerals occuring in igneous rocks, dark colored igenous rocks are usually denser than the ligher ones.

Light colored igneous rocks are part of what family?
The felsic family.
Light-colored igneous rocks are generally part of the?
felsic family
What kind of rocks make up most of the igneous group?
Basalt and other dark colored igneous rocks are the most with % of 66% and granite and other light to medium colored igneous rocks fill the other half with 44%
Light colored igneous rocks that are rich in aluminum potassium silicon and sodium are called what kind of rocks?
They're described as felsic igneous rocks.
What are light colored often intrusive igneous rocks containing a high percentage of silica called?
They are called felsic igneous rocks.
Why are dark igneous rocks heaver then light igneous rocks?
Dark igneous rocks usually have higher amounts of heavier elements such as iron. Light-colored igneous rocks tend to be richer in lighter elements like sodium and aluminum.
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.
Light-colored igneous rocks are less what than dark-colored igneous rocks are?
less dense
How does the density of a light colored rock differ from the density of dark colored 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.
Basaltic igneous rocks are?
Light colored
Why are granitic igneous rocks light in color?
granitic igneous rocks are light colored because of a lower density than basaltic rocks
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.
